* vulkan: Respect VK_KHR_portability_subset vertex stride alignment

We were hardcoding alignment to 4, but by specs it can be any values that

Fix partial updates for textures. (#4401)
I was forcing some types of texture to partially update when investigating performance with games that stream in data, and noticed that partially loading texture data was really broken on both backends.

Fixes Vulkan texture set by getting the correct expected size for the texture. Fixes partial upload on both backends for both Texture 2D Array and Cubemap using the wrong offset and uploading to the first layer/level for a handle. 3D might also be affected.

This might fix textures randomly having incorrect data in games that render to it - jumbled in the case of OpenGL, and outdated/black in the case of Vulkan. This case typically happens in UE4 games.

Vulkan: Flush command buffers for queries less aggressively (#4387)
The AutoFlushCounter would flush command buffers on any attachment change (write mask or bindings change) if there was a pending query. This is to get query results as soon as possible for draw skips, but it's assuming that a full occlusion query _pass_ happened, that we want to flush it's data before getting onto draws, rather than the queries being randomly interspersed throughout a pass that also draws.

Xenoblade 2 repeatedly switches between performing a samples passed query and outputting to a render target on each draw, and flips the write mask to do so. Flushing the command buffer every 2 draws isn't ideal, so it's best that we only do this if the pattern matches the large block style of occlusion query.

This change makes this flush only happen after a few consecutive query reports. "Consecutive" is interrupted by attachment changes or command buffer flush.

This doesn't really solve the issue where it resets more queries than it uses, it just stops the game doing it as often. I'm not sure of the best way to do that. The cost of resetting could probably be reduced by using query pools with more than one element and resetting in bulk.

Vulkan: Reset queries on same command buffer (#4329)
* Reset queries on same command buffer

Vulkan seems to complain when the queries are reset on another command buffer. No idea why, the spec really could be written better in this regard. This fixes complaints, and hopefully any implementations that care extensively about them.

This change _guesses_ how many queries need to be reset and resets as many as possible at the same time to avoid splitting render passes. If it resets too many queries, we didn't waste too much time - if it runs out of resets it will batch reset 10 more.

The number of queries reset is the maximum number of queries in the last 3 frames. This has been worked into the AutoFlushCounter so that it only resets up to 32 if it is yet to force a command buffer submission in this attachment.

This is only done for samples passed queries right now, as they have by far the most resets.

Vulkan: Explicitly enable precise occlusion queries (#4292)
The only guarantee of the occlusion query type in Vulkan is that it will be zero when no samples pass, and non-zero when any samples pass. Of course, most GPUs implement this by just placing the # of samples in the result and calling it a day. However, this lax restriction means that GPUs could just report a boolean (1/0) or report a value after one is recorded, but before all samples have been counted.

MoltenVK falls in the first category - by default it only reports 1/0 for occlusion queries. Thankfully, there is a feature and flag that you can use to force compatible drivers to provide a "precise" query result, that being the real # of samples passed.

Should fix ink collision in Splatoon 2/3 on MoltenVK.

Vulkan: Don't flush commands when creating most sync (#4087)
* Vulkan: Don't flush commands when creating most sync

When the WaitForIdle method is called, we create sync as some internal GPU method may read back written buffer data. Some games randomly intersperse compute dispatch into their render passes, which result in this happening an unbounded number of times depending on how many times they run compute.

Creating sync in Vulkan is expensive, as we need to flush the current command buffer so that it can be waited on. We have a limited number of active command buffers due to how we track resource usage, so submitting too many command buffers will force us to wait for them to return to the pool.

This PR allows less "important" sync (things which are less likely to be waited on) to wait on a command buffer's result without submitting it, instead relying on AutoFlush or another, more important sync to flush it later on.

Because of the possibility of us waiting for a command buffer that hasn't submitted yet, any thread needs to be able to force the active command buffer to submit. The ability to do this has been added to the backend multithreading via an "Interrupt", though it is not supported without multithreading.

OpenGL drivers should already be doing something similar so they don't blow up when creating lots of sync, which is why this hasn't been a problem for these games over there.

Improves Vulkan performance on Xenoblade DE, Pokemon Scarlet/Violet, and Zelda BOTW (still another large issue here)

* Add strict argument

This is technically a separate concern from whether the sync is a host syncpoint.

* Remove _interrupted variable

* Actually wait for the invoke

* Remove unused using.

GPU: Always draw polygon topology as triangle fan (#3932)
Polygon topology wasn't really supported and would only work on OpenGL on drivers that haven't removed it. As an alternative, this PR makes all cases of polygon topology use triangle fan. The topology type and transform feedback type have not been changed, as I don't think geo shader/tfb should be used with polygons.

The OpenGL spec states:
Only convex polygons are guaranteed to be drawn correctly by the GL.

For convex polygons, triangle fan is equivalent to polygon. I imagine this is probably how it works on device, as this get-out-of-jail-free card is too enticing to pass up.

This fixes the stat display in Pokemon S/V.

Vulkan: Don't create preload command buffer outside a render pass (#3864)
* Vulkan: Don't create preload buffer outside a render pass

The preload command buffer is used to avoid render pass splits and barriers when updating buffer data. However, when a render pass is not active (for example, at the start of a pass, or during compute invocations) buffer uploads can be performed at any time, so the optimization isn't as useful.

This PR makes it so that the preload command buffer is only used for buffer updates outside of a render pass. It's still used for textures as I don't want to shake things up right now regarding how the preload buffer is obtained before some other changes, and texture updates are a lot rarer anyways.

Improves performance slightly in Pokemon Scarlet/Violet (43 -> 48), as it was switching to compute, writing a bunch of buffers inline, then dispatching, then flushing commands... It uses 1 command buffer instead of 2 every time it does this now. Maybe it would be nice to find a faster way to sync without creating so many command buffers in a short period of time.

This was largely fine as the TextureStorage resources were being kept alive by the views holding their own references to them, but it also meant that dispose is only called as soon as the texture is created.

Aliased Storages are TextureStorages created with the same allocation as another TextureStorage, if they have to be aliased as another format. We keep track of a TextureStorage's `_aliasedStorages` as they are created, and dispose them when the TextureStorage is disposed...

...except it is disposed immediately, before any aliased storages are even created. The aliased storages added after this will never be disposed.

This PR attempts to fix this by disposing TextureStorage when its view count reaches 0. The other use of texture storage - the D32S8 blit - still manually disposes the storage, but regular uses created via the GAL are now disposed by the view count.

I think this makes the most sense, as otherwise in the future this behaviour might be forgotton and more things could be added to the Dispose() method that don't work due to it not actually calling at the right time.

This should improve memory leaks in Super Mario Odyssey, most noticeable when resolution scaling. The memory usage of the game is still wildly unpredictable due to how it interacts with the texture cache, but now it shouldn't get considerably longer as you play... I hope. I've seen it typically recover back to the same level occasionally, though it can spike significantly.

Please test a bunch of games on multiple GPUs to make sure this doesn't break anything.
