  Log Message:
  -----------
  [llvm][AArch64] Autoupgrade function attributes from Module attributes. (#82763)

sign-return-address and similar module attributes should be propagated to
the function level before got merged because module flags may contradict and
this information is not recoverable.
Generated code will match with the normal linking flow.

Refactored version of  (#80640).
Run the attribute copy only during IRMove.
