Moving generic constraint from extension to its member or vice versa may change the mangled name
of the member without changing the generic signature, thus introducing ABI breakages. This change
teaches the ABI checker to diagnose USR (mangled name) changes to cover such cases.

There is a reference to `std::string` being introduced without the necessary header being included.  Add the missing include.
