shader_recompiler: Implement AMD buffer bounds checking behavior. (#2448)

Browse source 
* shader_recompiler: Implement AMD buffer bounds checking behavior.

* shader_recompiler: Use SRT flatbuf for bounds check size.

* shader_recompiler: Fix buffer atomic bounds check.

* buffer_cache: Prevent false image-to-buffer sync.

Lowering vertex fetch to formatted buffer surfaced an issue where a CPU modified range may be overwritten with stale GPU modified image data.

* Address review comments.
