765c3f4e1f Allow draws with no descriptor set resources
The `descriptorSetWrites` being filled is now optional and the case of it being empty is handled correctly, this is done by certain titles such as ARMS and is entirely valid behavior. It should be noted that not doing this leads to errors in the guest due to invalid GPU state while working on the host GPU.

37327f1955 Fix and refactor SVC SignalToAddress/WaitForAddress
SVC `SignalToAddress` had a bug with the behavior of `SignalAndModifyBasedOnWaitingThreadCountIfEqual` which was entirely incorrect and led to deadlocks in titles such as ARMS that were dependent on it. This commit corrects the behavior and refactors both SVCs and moves their arbitration/waiting to inside the corresponding `KProcess` function rather than the SVC to avoid redundancies and improve code readability.

7206ab4c67 Fix exclusiveSubpass by finishing render pass at end
There was an oversight with exclusive subpasses which could lead to RPs with more than one subpass could be created even though one pass was exclusive, this oversight was not finishing the render pass at the end of `AddSubpass`. This could lead to a future subpass adding to the end of that RP even though it was intended to exclusively have a single subpass.

This case occurs in titles such as Celeste (in-game) and breaks rendering on GPUs that may require exclusive subpasses for proper functionality.

5d08d6e06f Disable unnecessary Khronos Validation Layer logs
The Khronos Validation Layer can often generate warning/error logs due to our intentional breakage from Vulkan specification, these can occur several times a frame resulting in the logs being spammed and making it difficult to extract useful information out of logs. The scope of these logs has now been reduced with more general filtering and the introduction of specialized filtering to handle complex cases such as BCn hacks with `libadrenotools` on Adreno devices.

23c9388caf Fix VK_KHR_push_descriptor-less path for descriptor set updates
Descriptor set updates were broken on the non-push-descriptor path due to lifetime issues with VkDescriptorSetLayout's usage during the execution phase which entirely broke rendering on AMD/Mali GPUs due to them not supporting `VK_KHR_push_descriptor`. 

This commit addresses that by moving the allocation of a descriptor set to outside the lambda and into the recording phase, it also simplifies the semantics and resources passed into the lambda by removing redundancies.

47bc3b4d99 Fix Render Pass Cache
The Vulkan render pass cache was fundamentally broken since it was designed around the Render Pass Compatibility clause due to being designed for framebuffer compatibility initially. As this scope was extended to a general render pass cache, the amount of data in the key was not extended to include everything it should have. This commit introduces the missing pieces in the RP cache and simplifies the underlying code in the process.

25a29f9044 Skip zero-initializing shader bytecode backing
The backing for shader data would implicitly be zero-initialized due to a `resize` on every shader parse, this was entirely unnecessary as we would overwrite the entire range regardless. 

We avoid this by using statically allocated storage and a span over it containing the shader bytecode which avoids any unnecessary clear semantics without resorting to more complex solutions such as a custom allocator.

42573170c6 Implement Framebuffer Cache
Implements a cache for storing `VkFramebuffer` objects with a special path on devices with `VK_KHR_imageless_framebuffer` to allow for more cache hits due to an abstract image rather than a specific one. 

Caching framebuffers is a fairly crucial optimization due to the cost of creating framebuffers on TBDRs since it involves calculating tiling memory allocations and in the case of Adreno's proprietary driver involves several kernel calls for mapping and allocating the corresponding framebuffer memory.

af7f0c301e Avoid redundant VkImageView recreation
There are a lot of cases of `VkImageView` being recreated arbitrarily due to it being tied to the ephemeral object `TextureView` rather than `Texture`, this commit flips that by storing all `VkImageView`s inside `Texture` with `TextureView` simply holding a copy of the handle to them. Additionally, this change results in stable `VkImageView` handles and helps in paving the path for framebuffer caching when `VK_KHR_imageless_framebuffer` is unavailable.

We run into a lot of successive subpasses with the exact same framebuffer configuration which we now exploit to avoid the creation of a new subpass due to the overhead involved with this. This provides significant performance boosts in certain cases due to the magnitude of difference in the amount of subpasses being created while providing next to no benefit in other cases.

de796cd2cd Implement overhead-free sequenced buffer updates with megabuffers
Previously constant buffer updates would be handled on the CPU and only the end result would be synced to the GPU before execute. This caused issues as if the constant buffer contents was changed between each draw in a renderpass (e.g. text rendering) the draws themselves would only see the final resulting constant buffer.

We had earlier tried to fix this by using vkCmdUpdateBuffer however this caused significant performance loss due to an oversight in Adreno drivers. We could have worked around this simply by using vkCmdCopy buffer however there would still be a performance loss due to renderpasses being split up with copies inbetween.

To avoid this we introduce 'megabuffers', a brand new technique not done before in any other switch emulators. Rather than replaying the copies in sequence on the GPU, we take advantage of the fact that buffers are generally small in order to replay buffers on the GPU instead. Each write and subsequent usage of a buffer will cause a copy of the buffer with that write, and all prior applied to be pushed into the megabuffer, this way at the start of execute the megabuffer will hold all used states of the buffer simultaneously. Draws then reference these individual states in sequence to allow everything to work without any copies. In order to support this buffers have been moved to an immediate sync model, with synchronisation being done at usage-time rather than execute (in order to keep contents properly sequenced) and GPU-side writes now need to be explictly marked (since they prevent megabuffering). It should also be noted that a fallback path using cmdCopyBuffer exists for the cases where buffers are too large or GPU dirty.

ddc9622b90 Fix Shader Module Cache
As bindings weren't correctly handled due to the fact that `EmitSPIRV` would change the bindings, the shader module cache would not correctly function and have no cache hits in `find` and rather have them in `try_emplace` which negated any performance benefit of it. This has now been fixed by retaining the initial cache key for insertion into the cache while also storing the post-emit bindings and restoring them during a cache hit.

Implements caching of the compiled shader module (`VkShaderModule`) in an associative map based on the supplied IR, bindings and runtime state to avoid constant recompilation of shaders.

372ab8befa Allow external synchronization for buffers
In certain situations such as constant buffer updates, we desire to use the guest buffer as a shadow buffer forwarding all writes directly to it while we update the host using inline buffer updates so they happen in-sequence. This requires special behavior as we cannot let any synchronization operations take place as they would break the shadow buffer, as a result, an external synchronization flag has been added to prevent this from happening. 

It should be noted that this flag is not respected for buffer recreation which will lead to UB, this can and will break updates in certain cases and this change isn't complete without buffer manager support.

b1f10865a0 Attach depth RT to command executor before draws
This enforces that the depth RT outlives the draw, without this the depth RT could be freed while in active use by command executor leading to UAFs and crashes.

ad0005f398 Remove guard-page from main thread stack
This was erroneously included while migrating from older code where stack creation was entirely handled with host constructs such as `mmap` directly to using `KPrivateMemory` to manage it, we would create a guard page with `mprotect` that the guest was unaware about and would cause a segfault when a guest accessed the extents of the stack as reported to the guest.

de81d28b1d Implement SVC GetThreadContext3
A partial implementation of the `GetThreadContext3` SVC, we cannot return the whole thread context as the kernel only stores the registers we need according to the ARMv8 ABI convention and so far usages of this SVC do not require the unavailable registers but all future usage must be monitored and potentially require extending the amount of saved registers.

36a7ad06bd Use built-in vibrator by default for controller #0
The vibration device had to be set manually prior which led to it generally not being set at all even though a user might want vibration, this commit fixes that by making controller #0 use the built-in vibrator by default.

b45437b78b Move Skyline internal files to external directory
Any Skyline files that should have been user-accessible were moved from `/data/data/skyline.emu/files` to `/sdcard/Android/data/skyline.emu/files` as the former directory is entirely private and cannot be accessed without either adb or root. This made retrieving certain data such as saves or loading custom driver shared objects extremely hard to do while this can be trivially done now.

e5e20f39c9 Implement a simple constant buffer cache
In some games such as SMO thousands of constant buffers are bound per frame which was causing an unreasonable number of lookups in both vmm and the buffer manager. Work around this by introducing a simple hashmap based cache, eviction is currently unsupported but not really necessary yet due to the small size of the buffers in the cache.

cb2614f80e Handle host accesses for NCE Memory Trapping API
We cannot ignore accesses from the host to a region protected by the NCE Memory Trapping API, there's often access to regions which have overlap with a protected region unintentionally and those accesses need to be handled correctly rather than leading to a crash. This is done by implementing an additional signal handler `NCE::HostSignalHandler` to lookup any potential traps on a `SIGSEGV` and handle them correctly or when there isn't a corresponding trap raise a `SIGTRAP` when debugger is connected or delegate to `signal::ExceptionalSignalHandler` when it isn't.

b04a0c386a Page out RW-trapped memory in NCE Memory Trapping
To cut down memory usage we now page out memory that is RW trapped via the NCE memory trapping API, the callbacks are supposed to page in the memory. This behavior is backed up by Texture/Buffer syncing which would read the host copies of data and write it to the guest, by paging the corresponding data on the guest we're avoiding redundant memory usage.

344c5f2a62 Implement RAII wrapper over file descriptors
The `FileDescriptor` class is a RAII wrapper over FDs which handles their lifetimes alongside other C++ semantics such as moving and copying. It has been used in `skyline::kernel::MemoryManager` to handle the lifetime of the ashmem FD correctly, it wasn't being destroyed earlier which can result in leaking FDs across runs.

7ce2a903a1 Update LLVM + Oboe
Initially this commit was only intended to update LLVM but due to a compilation error  on latest LLVM libcxx due to the C++ stdlib header `<algorithm>` being a transitive dependency that is no longer transitively included on the latest LLVM libcxx (as of https://reviews.llvm.org/D119667), this required changes in Skyline and Oboe which were done in https://github.com/google/oboe/pull/1521 and the submodule has been updated to include those changes.
