189b9533f2 Disable Vertex Buffers With 0 as IOVAs
A buffer with 0 as the start/end IOVA should be invalid as there shouldn't be any mappings at 0 in GPU VA, titles such as Puyo Puyo Tetris configure the Vertex Buffer with 0 IOVAs which leads to a segmentation fault without this exception.

cfeb8098db Attach TextureView/BufferView Lifetime to FenceCycle
The lifetime of a texture and buffer view is now bound by the `FenceCycle` in `CommandExecutor`, this ensures that a `VkImageView` isn't destroyed prior to usage leading to UB.

Support for clearing the depth/stencil RT has been added as its own function via either optimized `VkAttachmentLoadOp`-based clears or `vkCmdClearAttachments`.

Maxwell3D supports both independent and common color write masks like color blending but for common color write masks rather than having register state specifically for it, the state from RT 0 is extended to all RTs. It should be noted that color write masks are included in blending state for Vulkan while being entirely independent from each other for Maxwell, it forces us to use the `independentBlend` feature even when we are doing common blending unless the color write mask is common as well but to simplify all this logic the feature was made required as it supported by effectively all targeted devices.

baefb0fe93 Implement the Host1x command FIFO together with barebones Host1x classes
The Host1x block of the TX1 supports 14 separate channels to which commands can be issued, these all run asynchronously so are emulated the same way as GPU channels with one FIFO emulation thread each. The command FIFO itself is very similar to the GPFIFO found in the GPU however there are some differences, mainly the introduction of classes (similar to engines) and the Mask opcode (which allows writing to a specific set of offsets much more efficiently).

There is an internal Host1x class which functions similar to the GPFIFO class in the GPU, handling general operations such as syncpoint waits, this is accessed via the simple method interface. Other channels such as NVDEC and VIC are behind the 'Tegra Host Interface' (THI) in HW, this abstracts out the classes internal details and provides a uniform method interface ontop of the Host1x method one. We emulate the THI as a templated wrapper for the underlying class.

Syncpoint increments in Host1x are different to GPU, the THI allows submitting increment requests that will be queued up and only be applied after a specific condition in the associated engine is met; however the option to for immediate increments is also available.

debab7c9c7 Implement nvmap handle pinning/unpinning
nvmap allows mapping handles into the SMMU address space through 'pins'. These are refcounted mappings that are lazily freed when required due to AS space running out. Nvidia implements this by using several MRU lists of handles in order to choose which ones to free and which ones to keep, however as we are unlikely to even run into the case of not having enough address space a naive queue approach works fine. This pin infrastructure is used by nvdrv's host1x channel implementation in order to handle mapping of both command and data buffers for submit.

The offset of a member in a structure was determined by its relative position and compiler alignment. This is unoptimal for larger structures such as those found in GPU Engines that are primarily named by offset rather than relative positioning and end up requiring a massive amount of padding to function as is. A solution to this problem was simply to supply member offsets directly which can be done by using `OffsetMember` alongside a `union`.

414c0104c3 Rework Joy-Con Vibration Conversion
The guest -> host vibration conversion code was entirely broken as it didn't set the vibration `start`/`end` timestamps correctly for a cycle nor did it subtract from the `totalAmplitude` (`currentAmplitude` now) when it a cycle ended due to an incorrect `if` statement and contents. It would just end up saturating the amplitude as much as possible by adding more and more to `totalAmplitude` on every cycle while never subtracting which is entirely wrong and led to a very noticeable drop in amplitude when a vibration was repeated.

It's been entirely reworked to fix all the issues listed above and remove a lot of code that had no understandable purpose. More comments have also been added to the code to make it more readable with better variable and function naming alongside it.

These are used heavily in OpenGL games, which now, together with the
previous syncpoint changes, work perfectly. The actual implementation is
rather novel as rather than using a per-class state machine for all

the hot path of contiguous method execution and the performance loss is
negligible.

An issue with the initial layout of a texture being supplied as neither `VK_IMAGE_LAYOUT_UNDEFINED` or `VK_IMAGE_LAYOUT_PREINITIALIZED` was fixed, these cases are now handled by transitioning to those layouts after creating the image rather than supplying it within `initialLayout`.

Another issue was fixed regarding not maintaining a transformation after a surface has been destroyed and recreated existed and manifested itself when the user would go out of the app and come back in, they would see the surface having an identity transformation rather than the desired one.

KTransferMemory needs to be reset to RW on destruction unlike KSharedMemory which is simply freed on destruction, not emulating this behavior accurately leads to `deko_examples` from `switch-examples` to lead to a SEGFAULT on selecting an example as it expects the memory to be R/W while it ends up being freed instead

d45193874e Fix NvDrv CloseDevice Bug
The unique pointer to a device in the map was simply reset rather than deleting the entry from the map, this resulted in the device not being properly closed and when the device was reopened then the `emplace` was a NOP as the entry already existed. This resulted in a `nullptr` dereference down the line when an application attempted to issue an IOCTL to a device that was previously closed and reopened. This is known to occur in Deko3D as it recreates the context when loading an example which includes closing and reopening devices.

02bcf98b8c Fix NvDrv Bugs + NACP Parsing Bug
A hotfix for a nvdrv bug where an IOCTL with no input/output buffers would crash and a major `nvmap` bug which broke the `FromId` IOCTL as it didn't write back the handle ID, another minor bug existed in `nvhost` where the `ZCullGetInfo` IOCTL was `INOUT` rather than `OUT`.

A bug with NACPs was also fixed caused by incorrect padding for the `NacpData` structure which resulted in the `saveDataOwnerId` member being read incorrectly and as a result the save data folder being incorrect.

It should be noted that `preallocatedBufferCount` (previously `hasBufferCount`) and `activeSlotCount` were adapted accordingly with how they were effectively the same value as all active buffers were preallocated prior but now there can be a non-preallocated active slot. 
Additionally, a bug has been fixed where `SetPreallocatedBuffer` has the graphic buffer as an optional argument whereas it was treated as a mandatory argument prior and could lead to a SEGFAULT if an application were to not pass in a buffer.

It has now been optimized to only do a wake if any waiting thread needs to be awoken.

216e5cee81 Separate Guest and Host Presentation + AChoreographer V-Sync Event
We had issues when combining host and guest presentation since certain configurations in guest presentation such as double buffering were very unoptimal for the host and would significantly affect the FPS. As a result of this, we've now made host presentation have its own presentation textures which are copied into from the guest at presentation time, allowing us to change parameters of the host presentation independently of the guest.

We've implemented the infrastructure for this which includes being able to create images from host GPU memory using VMA, an optimized linear texture sync and a method to do on-GPU texture-to-texture copies.

We've also moved to driving the V-Sync event using AChoreographer on its on thread in this PR, which more accurately encapsulates HOS behavior and allows games such as ARMS to boot as they depend on the V-Sync event being signalled even when the game isn't presenting.

A minor change regarding the type of the `Fps` and `Frametime` globals was changed to `skyline::i32`s which is a more suitable type due to those having a smaller chance of overflowing while being signed as Java doesn't have unsigned integral types.

This is based off my own glue RE and Thog's time RE.

34cb0b49e8 Implement the entirety of time services
This reimplements our time backend to be significantly more accurate to
the real PSC and provides complete implementations for every time IPC
allowing many newer games to work properly.

Time is unique in its use of glue services, the core sysmodule is fully
isolated and doesn't interface with any other services. Glue is instead
used where that is needed (e.g. for fetching settings), this distinction
is also present in our implementation.

Another unique feature of time is its global state, as time is
calibrated from the start of the service its state cannot be lost as
that would result in the application offsetting time incorrectly
whenever it closed a session.

A large proportion of this is based off of Thog's 9.0.0 PSC reversing.

63c54207d2 Add AndroidAsset{Backing,FileSystem} for accessing built-in assets
These only implement the subset of VFS needed for time, implementing
more is difficult due to some issues in the AAsset API which make
support quite ugly. The abstract asset filesystem can be accessed by
services through the OS class allowing other implementations to be used
in the future.

937e3d6f68 Add endiannes swapping helper functions
Avoid using compiler functions manually to create a cleaner interface,
and allow swapping the endianness of arbritary lengths.

def9f96b02 Add a ResultValue helper class to simplify result handling
This is a very common usecase for result handling and allows much
cleaner code.

e90dd672af Fix Clock Rescaling Bug (Introduced in #135)
There was a mistake in the code-style refactor where the signature in the instruction encoding of `MRS` was set to `0xD54` instead of `0xD53` which would cause a SIGILL (Illegal Instruction) for devices which had their HW timer frequency equivalent to the Switch (19.2MHz) as a modified `MRS` would be deployed there. This issue should not affect devices which perform clock rescaling as the `MRS` instruction there is encoded by the assembler.

6390561f0f Fixup VFS error checking
Many users of VFS didn't check for nullptr or 0 results leading to
various potential issues, to mitigate this introduce error checking to
VFS by default. The original variants can still be used through the
*Unchecked family of functions.
