[ObjCInterop] Implement @ObjCSignatureOverride

This annotation leads to conflicting overloads error supression,
in case where several function with the same argument types,
but different argument names are inherited from ObjC class.

We need to implement it in both K1 and K2 to make the IDE experience
better.
But the annotation itself wouldn't be available in K1.
