This change makes sure that `NSNotification.Name.NEVPNStatusDidChange` is imported correctly when C++ interop is enabled. `importer::findSwiftNewtype` is called while writing Clang modules, at a point when the translation-unit scope does not exist (`clangSema.TUScope` is `nullptr`). That prevents the Clang lookup from discovering `NSNotificationName` declaration. Instead of trying to pass a translation-unit scope to Clang, let's use qualified name lookup which does not require a scope. rdar://112199372
