  [AMDGPU][gfx12] Clean-up implementation of waits before SCOPE_SYS stores

We can do it all in finalizeStore if we ensure it always sees the stores.
For that, I needed to fix a hidden bug where finalizeStore wouldn't see all stores
because sometimes the iterator got out-of-sync and didn't point to the store anymore.

This also removes the waits before volatile LDS stores which never needed it, that was a bug until now.
