Add support for large sampler arrays on Vulkan (#6489)

* Add support for large sampler arrays on Vulkan

* Shader cache version bump

* Format whitespace

* Move DescriptorSetManager to PipelineLayoutCacheEntry to allow different pool sizes per layout

* Handle array textures with different types on the same buffer

* Somewhat better caching system

* Avoid useless buffer data modification checks

* Move redundant bindings update checking to the backend

* Fix an issue where texture arrays would get the same bindings across stages on Vulkan

* Backport some fixes from part 2

* Fix typo

* PR feedback

* Format whitespace

* Add some missing XML docs
