elm_list & elm_genlist & elm_gengrid: fix the behavior of using the mouse.

Summary:
Elementary widgets have different behavior of using the mouse, they need to be unified.
- swipe : without checking on hold, just checking drag state.
- longpress : after longpress, _item_unhighlight(), _item_unselect() are called.
- select : when the mouse pointer leaves item area, _item_unhighlight(), _item_unselect() are called.
