edje/calc: correctly handle swallow/group objects as clippers for state clips

Summary:
in the case where the clipper being set was an indirect object, it's necessary
to resolve the lookup for that part and use the actual part object to avoid
setting a placeholder rect as the clipper

@fix
Depends on D8850
