* Fix #6544: Properly format nested type names in extensions

Modify DeclRefBase::toText to properly handle types defined
in extensions by qualifying them with their parent type name.
This ensures getFullName() returns the full name like
'FullPrecisionOptimizer<half>.State' instead of just '.State'.
Also handle other nested types in structs/classes similarly.

* Update extension reflection handling - with generics args and namespaces

- stopping namespace inclusion for extension members
- Update to use getTargetType() to handle the generic arguments
- update test cases

* Simplify code to remove using parentDecl
