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