Enable the runtime to discover protocol conformances for types wrapped from ObjC
The strategy we are using is to obtain the class name from the ObjC runtime (as apparently nominal type descriptor for ObjC-wrapped types do not contain a useful name string) and then crafting the appropriate mangled name for the witness
Also, make AppKit another source of conformances. We currently have custom conformances for Reflectable that we are in Foundation (NSURL) and AppKit (NSView) - if more modules need to have custom mirrors, we might end up having to expand the list
