atspi: Improves how to find the can_highlight of the widget.

   Returns EINA_FALSE if any of parents is EINA_FALSE
   when determining can_highlight.
   To determine can_highlight for the parent of an object,
   we try to find the parent of the parent again.
   As it repeats, it traverses as much as depth size factorial (d!)
   However, if any of the parent of the object has can_highlight of the widget data is EINA_FALSE,
   it is eventually EINA_FALSE
