If ecore get the mouse cancel event(ex: display off, or window stack change) from below, we need to deal with.
Currently, evas also generates up event using evas_event_feed_mouse_cancel function when window hide is called.
if cancel event occurs, ecore also call evas_event_mouse_feed_cancel like window hide situation.
cancel event means all button or touch event should be canceled, but in the future, if we need to deal each cancel event according to touch point,
we need to add api like evas_event_feed_multi_cancel
