* Fix TXQ for 3D textures.
Assumes the texture is 3D if the component mask contains Z.
This fixes a bug in UE4 games where parts of the map had garbage pointers to lighting voxels, as the lookup 3D texture was not being initialized. Most notable game is THPS1+2.
May need another PR to keep image store data alive and properly flush it in order using the AutoDeleteCache.
* Get sampler type for TextureSize from bound textures.
* Move shader resource descriptor creation out of the backend
* Remove now unused code, and other nits
* Shader cache version bump
* Nits
* Set format for bindless image load/store
* Fix buffer write flag
* Support separate textures and samplers
* Add missing bindless flag, fix SNORM format on buffer textures
* Add missing separation
* Add comments about the new handles
