Matt Arsenault e108853ac8 clang: Allow targets to set custom metadata on atomics (#96906) ...

Use this to replace the emission of the amdgpu-unsafe-fp-atomics
attribute in favor of per-instruction metadata. In the future
new fine grained controls should be introduced that also cover
the integer cases.

Add a wrapper around CreateAtomicRMW that appends the metadata,
and update a few use contexts to use it.
