ivi-shell: add new method to remove a callback to get notificaiton of ivi_layer property changes.
To get property changes of ivi_layer, callbacks can be registered.
However there was no API to remove a callback rather than removing all
callbacks by using layer_remove_notification.
layer_remove_notification_by_callback can do it.
