When a structural refinement member has a type that is a type alias for a generic derived value class, the boxing wrapper in `maybeBoxingCast` synthesized a `New` on the alias, which provided only the alias' partial type arguments to the underlying class constructor and failed with "Not enough type arguments". Dealias the widened type before constructing the `New` so the underlying value class receives its full type argument list. Fixes scala#24056
