clutter-event: Add device added/removed events

Browse Source 
Add clutter device added and removed events to allow processing of them as
it happens in the backends, queuing them and performing actions in order.

This allows not to loose any event that is performed just before removing or
disabling a device, and still process the events in order in the event
queue.
