Fix TXQ for 3D textures. (#2613)

Browse Source 
* 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.
