bind,cmd: accept ObjC wrapper types in bound packages

Browse Source 
Accept ObjC API wrapper types as arguments and return values from
bound Go package functions and methods. Also, allow Go structs
to extend ObjC classes and implement ObjC protocols as well as override
and implement methods.

This is the third and final part of the implementation of the golang/go#17102
proposal.

Fixes golang/go#17102
