This fixes a longstanding issue with resolution scale that could result in flickering graphics, typically the first frame something is drawn, or on camera cuts in cutscenes.
The root cause of the issue is that texture scale can be changed when binding textures or images. This typically happens because a texture becomes a view of a larger texture, such as a 400x225 texture becoming a view of a 800x450 texture with two levels. If the 400x225 texture is bound as a render target and has state [1x Undesired], but the storage texture is [2x Scaled], the render target texture's scale is changed to [2x Scaled] to match its new storage. This means the scale changed after the render target state was processed...
This can cause a number of issues. When render target state is processed, texture scales are examined and potentially changed so that they are all the same value. If one texture is scaled, all textures must be. If one texture is blacklisted from scaling, all of them must be. This results in a single resolution scale value being assigned to the TextureManager, which also scales the scissor and viewport values.
If the scale is chosen as 1x, and a later texture binding changes one of the textures to be 2x, the scale in TextureManager no longer matches all of the bound textures. What's worse, the scales in these textures could mismatch entirely. This typically results in the support buffer scale, viewport and scissor being wrong for at least one of the bound render targets.
This PR fixes the issue by re-evaluating render target state if any scale mismatches the expected scale after texture bindings happen. This can actually cause scale to change again, so it must loop back to perform texture bindings again. This can happen as many times as it needs to, but I don't expect it to happen more than once. Problematic bindings will just result in a blacklist, which will propagate to other bound targets.

* WIP barrier batch
* Add store op to image usage barrier
* Dispose the barrier batch
* Fix encoding?
* Handle read and write on the load op barrier.
Load op consumes read accesses but does not add one, as the only other operation that can read is another load.
* Simplify null check
* Insert barriers on program change in case stale bindings are reintroduced
* Not sure how I messed this one up
* Improve location of bindings barrier update
This is also important for emergency deferred clear

* 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

The case where it's not hardware accelerated will do the check integer-wise anyways.

* GPU: Don't create tracking handles for buffer textures
Buffer texture memory is handled by the buffer cache - the texture shouldn't create any tracking handles as they aren't used. This change simply makes them create and iterate 0 tracking handles, while keeping the rest of the texture group around.
This prevents a possible issue where many buffer textures are created as views of overlapping buffer ranges, and virtual regions have many dependant textures that don't actually contribute anything to handle state.
Should improve performance in Mortal Kombat 1, possibly certain UE4 games when FIFO raises to 100%.

#5576 changed where the position was declared, but forgot to add the Invariant declaration to position when the ReducedPrecision flag was enabled. This was causing weird graphical bugs in a bunch of games, mostly to do with mismatching depth between multiple draws of the same geometry.
Maybe the attempt to add it to Position in DeclareInputOrOutput can be removed now, assuming that path is never used.
