ivi-shell: add new method to remove a callback to get notification of ivi_surface property changes.
To get property changes of ivi_surface, callbacks can be registered.
However there was no API to remove a callback rather than remove all
callbacks by using surface_remove_notification.
surface_remove_notification_by_callback can do it.
