ivi-shell: rework configure_surface notification

Browse Source 
The add_notification_configure_surface API accepts a simple
wl_listener instead of a ivi-shell specific notification
function. Therefore, the API is renamed to
add_listener_configure_surface.

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.

The remove API is removed too:
- ivi_layout_remove_notification_configure_surface
