[Runtime] Use a prefix Objective-C protocol layout to extract the name.
[Runtime] Use a prefix Objective-C protocol layout to extract the name.

Introduce TargetObjCProtocolPrefix, which describes just enough of the
Objective-C runtime’s Protocol structure to extract the name without
having to call Objective-C’s protocol_getName().
