Fix some layering violations where CGObjCMac's NSString emission was

performed at the CodeGenModule level.

Would be NFC except we now also use a different uniquing structure so
that we don't get spurious conflicts if you ask for both an NSString
and a CFString for the same content (which is possible with builtins).
