* Vulkan: Use staging buffer for temporary constants
Helper shaders and post processing effects typically need some parameters to tell them what to do, which we pass via constant buffers that are created and destroyed each time.
This can vary in cost between different Vulkan drivers. It shows up on profiles on mesa and MoltenVK, so it's worth avoiding. Some games only do it once (BlitColor for present), others multiple times. It's also done for post processing filters and FSR upscaling, which creates two buffers.
For mirrors, I added the ability to reserve a range on the staging buffer for use as any type of binding. This PR allows these constant buffers to be instead temporarily allocated on the staging buffer, skipping allocation and buffer management costs entirely.
Two temporary allocations do remain:
- DrawTexture, because it doesn't have access to the command buffer scope
- Index buffer indirect conversion, because one of them is a storage buffer and thus is a little more complicated.
There's a small cost in that the uniform buffer takes up more space due to alignment requirements. At worst that's 256 bytes (on a GTX 1070) but more modern GPUs should have a better time.
Worth testing across different games and post effects to make sure they still work.
* Use temporary buffer for ConvertIndexBufferIndirect
* Simplify alignment passing for now
* Fix shader params length for CopyIncompatibleFormats
* Set data for helpershaders without overlap checks
The data is in the staging buffer, so its usage range is guarded using that.
Turns out that ElementAt for Queue<T> runs the default implementation as it doesn't implement IList, which enumerates elements of the queue up to the given index. This code was creating `count` enumerators and iterating way more queue items than it needed to at higher counts. The solution is just to use one enumerator and break out of the loop when we get the count that we need.
3.5% of backend time was being spent _just_ enumerating at the usual spot in SMO.
This prevents a small allocation each time this method is called. This is a top 3 SOH allocation during gameplay in most games, and eliminating it is pretty free.

* GPU: Add fallback when textureGatherOffsets is not supported.
This PR adds a fallback for GPUs or APIs that don't support an equivalent to the method `textureGatherOffsets`, where each of the 4 gathered texels has an individual offset. This is done by reusing the existing code to handle non-const offsets for texture instructions, though it has also been corrected as there were a few implementation issues.
MoltenVK reports support for this capability, and it didn't error when we initially released the MacOS build, but that has since changed. MVK still reports support, but spirv-cross has been fixed in a way that it _attempts_ to use this capability, but the metal compiler errors since it doesn't exist.
Some other fixes:
- textureGatherOffsets emulation has been changed significantly. It now uses 4 texture sample instructions (not gather), calculates a base texel (i=0 j=0) and adds the offsets onto it before converting into a tex coord. The final result is offset into a texel center, so it shouldn't be subject to interpolation, though this isn't perfect and could have some error with floating point formats with linear sampling. It is subject to texture wrap mode as it should be, which is why texelFetch was not used.
- Maybe gather should be used here with component `w` (i=0, j=0), though this multiplies number of texels fetched by 4... The way it was doing this before _was_ wrong_, but doing it right would avoid issues with texel center precision.
- textureGatherOffset (singular) now performs textureGather with the offset applied to the coords, rather than the slower fallback where each texel is fetched individually.
* Increment shader cache version, remove unused arg
* Use base texture size for gather coord offset.
Implicit LOD for gather is not supported.
* Use 4 texture gathers for offsets emulation
Avoids issues with interpolation at cost of performance

* Remove compute stage from read to write barriers

* Set PipelineStateFlags based on supported stages
Just some simple changes to the buffer conversion shaders. (stride conversion, D32S8 to D24S8)
The first change is using a device local buffer for converted vertex buffers, since they're only read/written on the GPU. These paths don't trigger on NVIDIA, but if you force them to use it demonstrates the full extent writing to host owned memory from compute absolutely destroys them. AMD GPUs are less heavily affected by this issue, but since the game in question was writing 230MB from compute, I imagine it should have some effect.
The second change is allowing the buffer conversion shaders to scale their work group count. While dividing the work between 32 invocations works OK for M1 macs, it's not so great for anything with more cores like AMD GPUs, which should be able to do a lot more parallel copies. Now, it scales by roughly 100 elements per invocation.
Some stride change cases could be improved further by either limiting vertex buffer size somehow (reading the index buffer could help, but is always risky) or only updating regions that changed, rather than invalidating the whole thing.
* Implement vertex and geometry shader conversion to compute
* Call InitializeReservedCounts for compute too
* PR feedback
* Set clip distance mask for geometry and tessellation shaders too
* Transform feedback emulation only for vertex
* Move shuffle handling out of the backend to a transform pass
* Handle subgroup sizes higher than 32
* Stop using the subgroup size control extension
* Make GenerateShuffleFunction static
* Shader cache version bump
* Vulkan: Periodically free regions of the staging buffer
There was an edge case where a game could submit tens of thousands of small copies over the course of over half a minute to unique fences. This could result in a large stutter when the staging buffer became full and it tried to check and free thousands of completed fences.
This became visible with some games and mirrors on Windows, as they don't submit any buffer data via the staging buffer, but may submit copies of the support buffer.
This change makes the Vulkan backend check for staging buffer completion on each command buffer submit, so it can't get backed up with 1000s of copies to check.

Command buffer errors currently trigger an exception "DeviceLost" crashing the process.
Looking at [MKV's code](53a4eb26f2/MoltenVK/MoltenVK/GPUObjects/MVKQueue.mm (L392-L408)) we observe that:
- It hard fails if error is:
```
MTLCommandBufferErrorBlacklisted || MTLCommandBufferErrorNotPermitted || MTLCommandBufferErrorDeviceRemoved
```
- Otherwise fails conditionally if `config.resumeLostDevice == false` (current default)
For Ryujinx's use-case it's more graceful to resume on those errors rather than crashing the app, the error isn't totally silenced since `mvk` still logs it
Fixes#4704, #4575
* Vulkan: Batch vertex buffer updates
Some games can bind a large number of vertex buffers for draws. This PR allows for vertex buffers to be updated with one call rather than one per buffer.
This mostly affects the AMD Mesa driver, the testing platform was Steam Deck with Super Mario Odyssey. It was taking about 12% before, should be greatly reduced now.
A small optimization has been added to avoid looking up the same buffer multiple times, as a common pattern is for the same buffer to be bound many times in a row with different ranges.
* Only rebind vertex buffers if they have changed
* Address feedback
Our Vulkan backend inserts image barriers when a texture is sampled after it is rendered. This is done via a "modification flag" which is set when a render target is unbound (presuming that a texture has finished drawing to it).
Imagine the following scenario:
- Game sets render target to texture A
- Game renders to texture A
- (render pass ends)
- Game binds texture A to a sampler
- Game sets render target to texture B
- Renders to texture B using texture A (barrier required)
Because of the previous behaviour, the check to add a barrier for sampling a texture actually happens before it is registered as modified, meaning no barrier was added at all. This isn't always the case, but it was definitely causing issues in Xenoblade 2.
This doesn't fix any more complicated issues where a texture is repeatedly sampled while it is currently being rendered.
Fixes visual glitches at lower resolutions in Xenoblade 2. May fix other cases.
