  [mlir][ROCDL][AMDGPU] Add result arguments to buffer atomics (#198596)

Buffer atomic operations were failing LLVM validation because they
weren't declared as having a result (the old value). This commit updates
those operations to fix the error. (Note: if you don't need the result,
you just don't use it, and the compiler backend emits an atomic that
doesn't return the old value.)
