This CL introduces variance-dependent treatment of the `Handle` native type when converting native types to Dart types. Since `Handle` can represent any object, it should match any type. To achive that in cases when `Handle` appears as the subtype in the subtype checks, it's converted to `Never` in covariant positions and to `Object?` in covariant ones.
