ui/gtk: enable backend to send multi-touch events

GTK3 provides the infrastructure to receive and process multi-touch
events through the "touch-event" signal and the GdkEventTouch type.
Make use of it to transpose events from the host to the guest.

This allows users of machines with hardware capable of receiving
multi-touch events to run guests that can also receive those events
and interpret them as gestures, when appropriate.

An example of this in action can be seen here:
