  [AMDGPU] Refactor insertRelease into insertWriteback + insertWait (NFC) (#199486)

A release consists of two actions: write-back the current cache, and
wait for "relevant" outstanding operations to complete. With the new
memory model, it is possible to disable the cache write-back using
"non-av". This patch cleanly separates the existing implementation so
that the write-backs can be selectively applied after checking for
non-av semantics.

Part of a stack:

- #199486
- #199621
- #199489 
- #199622
