Robert Findley 1170771074 go/types, types2: set an origin object for vars and funcs
Historically, Objects in go/types were canonical, meaning each entity
was represented by exactly one variable and could thus be identified by
its address. With object instantiation this is no longer the case: Var
and Func objects must be copied to hold substituted type information,
and there may be more than one Var or Func variable representing the
same source-level entity.

This CL adds Origin methods to *Var and *Func, so users can efficiently
navigate to the corresponding canonical object on the generic type.

Fixes #51682
