b91ce939a2 Introduce CI build signing
We've done no signing of any Skyline APKs to date which causes issues regarding authenticity of any APKs as they could be entirely unofficial builds which have not been vetted by the team. Additionally, the different keys remove the ability to reinstall a different build successively as Android checks for matching signatures before installing an APK.

e1cc8676cf Add option to view internal directory
With the Skyline document provider, easy access to the internal directory is required which may be hard to navigate to through the system file manager. This adds an option in settings to directly open up the directory in the system file manager.

ba97985b55 Revise DocumentsProvider URI structure
The URIs (Document ID + Root) of the Skyline `DocumentsProvider` was unoptimal as it wasn't relative to a base directory. This is required for opening a root without knowledge of the full path in advance, it is therefore cleaner to provide a uniform `ROOT_ID` in a companion class.

ee7da31fc6 Add DocumentProvider for accessing internal files
On Android 12 and above, files from an application's external storage directory cannot be accessed by the user. The only proper SAF-compliant way to solve this is to create a `DocumentProvider` which proxies access to internal storage accordingly.

80c8fb8791 Implement CPU BCn Texture Decoding
Certain GPU vendors such as ARM's Mali do not have support for BCn textures whatsoever while other vendors such as AMD only have partial support (BC1-BC3). Most titles on the guest utilize BC textures and to address this on host GPUs without support for BCn, we need to decompress the texture on the CPU. This commit implements a CPU BCn texture decoder based off Swiftshader's BC decoder, it also adds the necessary infrastructure to have different formats for the `GuestTexture` and `Texture` objects.

fe615b1e03 Clarify texture swizzling inner-loop iteration count
The iterations of the inner loop for sector deswizzling was miscalculated as `SectorWidth * SectorHeight` while the result was correct at `32`, it should be determined by the amount of sector lines within a GOB i.e.: `(GobWidth / SectorWidth) * GobHeight`.

7d4e0a7844 Implement Mipmapped Texture Support
Support for mipmapped textures was not implemented which is fairly crucial to proper rendering of games as the only level that would load is the first level (highest resolution), that might result in a lot more memory bandwidth being utilized. Mipmapping also has associated benefits regarding aliasing as it has a minor anti-aliasing effect on distant textures. 

This commit entirely implements mipmapping support but it does not extend to full support for views into specific mipmap levels due to the texture manager implemention being incomplete.

da7e6a7df7 Replace Maxwell DMA GuestTexture usage with new swizzling API
Maxwell DMA requires swizzled copies to/from textures and earlier it had to construct an arbitrary `GuestTexture` to do so but with the introduction of the cleaner API, this has become redundant which this commit cleans up and replaces with direct calls to the API with all the necessary values.

de300bfdbe Refactor Texture Swizzling
The API for texture swizzling is now more concrete and abstracted out from `GuestTexture`, this allows for neater usage in certain areas such as MaxwellDMA while having a `GuestTexture` wrapper as well allowing for neater usage in those cases. 

The code itself has also been cleaned up slightly with all usage of `u32`s being upgraded to `size_t` as this is simply more efficient due to the compiler not needing to emulate wraparound behavior for integer types smaller than the processor word size.

0a3cf25823 Implement the Fermi 2D blitting engine
The Fermi 2D engine implements both image blit and resolve operations, supporting subpixel sampling with both linear and point filtering.

Resolve operations are performed by sampling from the center of each pixel in order to resolve the final image from the MSAA samples
MSAA images are stored in memory like regular images but each pixels dimensions are scaled: e.g for 2x2 MSAA
```
112233
112233
445566
445566
```
These would be sampled with both duDx and duDy as 2 (integer part), resolving to the following:
```
123
456
```
Blit operations are performed by sampling from the corner of each pixel, scaling the image as one would expect.

This implementation isn't fully complete as Vulkan blit doesn't support some combinations which Fermi does, most notably between colour and depth stencil. These will be implemented properly at a later date, likely after the texture manager rework.
Out of Bounds Blit, used by some OpenGL games is also missing since supporting it requires texture aliasing, this will also be supported after the texture manager rework.

In the Maxwell 3D engine, instanced draws are implemented by repeating the exact same draw in sequence with special flag set in vertexBeginGl. This flag allows either incrementing the instance counter or resetting it, since we need to supply an instance count to the host API we defer all draws until state changes occur.

We found out that certain vendors such as Nvidia had a limitation on the global priority of a queue and requesting `VK_QUEUE_GLOBAL_PRIORITY_HIGH_EXT` would result in `VK_ERROR_NOT_PERMITTED_EXT`. A quirk has been introduced to supply the maximum supported global priority which is currently set on a per-vendor basis to avoid future crashes.

7ef4959060 Implement Graphics Pipeline Cache
Implements a cache for storing `VkPipeline` objects which are fairly expensive to create and doing so on a per-frame basis was rather wasteful and consumed a significant part of frametime. It should be noted that this is **not** compliant with the Vulkan specification and **will** break unless the driver supports a relaxed version of the Vulkan specification's Render Pass Compatibility clause.

50a8b69f7b Optimize descriptor set writes using push descriptors
We can use inline push descriptors for writing to descriptor rather than allocating a descriptor set for a one time write and freeing it as this is rather inefficient while an inline push descriptor generally ends up being a direct `memcpy` on the driver side designed for this use-case.

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.

02f99273ac Implement Shader Module Cache
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. This doesn't entirely address shader compilation as an issue since host shader compilation is tied to Vulkan pipeline objects rather than Vulkan shader modules, they need to be cached to prevent costly host shader recompilation.
