ivi-shell: rework surface_add_notification API 

The surface_add_notification API accepts a simple
wl_listener instead of a ivi-shell specific notification
function. Therefore, the API is renamed to surface_add_listener.

This change has several advantages:
1. Code cleanup
2. No dynamic memory allocation. Listeners are allocated
   by controller plugins
3. Remove API is not needed. Controller plugins can easily
   remove the listener link.

This patch also remove two APIs which are not needed:
- ivi_layout_surface_remove_notification
- ivi_layout_surface_remove_notification_by_callback
