Change how DeclRef::toText works (#5592)

* Change how DeclRef::toText works

We now ignore the decl-ref heirarchy since that only includes nodes with specialization info & simply walk up the tree of decls, while emitting any specializations present in the decl-ref.

* Update some tests. Add cases for direct refs to generic params & Lookup decl refs
