shader_recompiler: Implement render target swizzles when no format is available (#739)

* shader_recompiler: Use null image when shader is compiled with unbound sharp

* video_core: Refactor and render target swizzles

* liverpool_to_vk: Add missing swap format from RDR

* video_core: Refactor shader recompiler interface

* Makes it much easier to pass runtime information to the recompiler and have it treated as part of the shader key. Also pulls out most runtime state from Info struct

* shader_recompiler: Avoid some asserts
