9b4b4ae585 types2, go/types: fix instantiation of named type with generic alias
The typechecker is assuming that alias instances cannot be reached from
a named type. However, when type parameters on aliases are permited, it
can happen.

This CL changes the typechecker to propagate the correct named instance
is being expanded.

Updates #46477
Fixes #68580
