efl_ui: remove Efl.Ui.Clickable from containers

Summary:
these widgets here are containers, means: they contain items that can be
clicked, but the container itself cannot be clicked. Later on, we should
introduce a new interface which contains events that reflect the clicked
event of theire items.
