Evas: Add API to access private function

We need a function in DnD for the overlapping feature to retrieve all
the objects at a specific position.
A private function exists in Evas (evas_event_objects_event_list) for
that purpose.
We need an access to this function for Elementary but we don't
want the is_frozen flag to be checked.
