Allow texture arrays to use separate descriptor sets on Vulkan (#6870)

* Report base and extra sets from the backend

* Pass texture set index everywhere

* Key textures using set and binding (rather than just binding)

* Start using extra sets for array textures

* Shader cache version bump

* Separate new commands, some PR feedback

* Introduce new manual descriptor set reservation method that prevents it from being used by something else while owned by an array

* Move bind extra sets logic to new method

* Should only use separate array is MaximumExtraSets is not zero

* Format whitespace
