efl: add autodel option to EvasObject

By passing autodel=false to class EvasObject, this allows us to wrap
an Evas_Object* where the underlying pointer lifetime is managed by
some other internal object, hence telling the EvasObject instance to
avoid deleting the underlying pointer when the EvasObject itself is
destroyed.
