shader_recompiler: Replace texel buffers with in-shader buffer format interpretation (#2363)

Browse source 
* shader_recompiler: Replace texel buffers with in-shader buffer format interpretation

* shader_recompiler: Move 10/11-bit float conversion to functions and address some comments.

* vulkan: Remove VK_KHR_maintenance5 as it is no longer needed for buffer views.

* shader_recompiler: Add helpers for composites and bitfields in pack/unpack.

* shader_recompiler: Use initializer_list for bitfield insert helper.
