584c83cb - [Clang][AMDGPU] Add clang builtins for buffer format load/store intrinsics (#187064)

[Clang][AMDGPU] Add clang builtins for buffer format load/store intrinsics (#187064) Adding new clang builtins for AMDGPU raw/struct buffer format load/store intrinsics. Clang currently has `__builtin_amdgcn_raw_buffer_load_b*` and `__builtin_amdgcn_raw_buffer_store_b*` builtins, but is missing builtins for the format variants. These format intrinsics are currently used by device-libs via manually written IR wrappers in [buffer-intrinsics.ll](https://github.com/ROCm/llvm-project/blob/amd-staging/amd/device-libs/ockl/src/buffer-intrinsics.ll).
