AMDGPU: Remove .v2bf16 buffer atomic fadd intrinsics (#95783)
These are redundant with the unsuffixed versions, and have a name collision with surprising behavior when the base intrinsic is used with v2bf16. The global and flat variants should be removed too, but those are complicated due to using v2i16 in place of the natural v2bf16. Those cases can soon be completely deleted in favor of atomicrmw. The GlobalISel codegen change is broken and substitutes handling as bf16 for handling as f16, but it's a bug that this passed the IRTranslator in the first place.
