[PATCH] D54542: Remove unused getMDNodeFwdRefOrNull interfaces (NFC)

@steven_wu I realized there are still some uses of the internal getMDNodeFwdRefOrNull implementation, so just removed the external interfaces. It seemed like switching to returning ErrorOr<MDNode*> actually made things more complicated, so I just tried to improve the existing error messages. Let me know if you have something else in mind.
