gdk: Ignore synthesized leave events out of touch events

Browse Source 
Certain crossing modes notify about synthesized events, where
the pointer didn't really leave the window. Unsetting the stage
from the device at that time is incorrect, and will leave all
remaining touches unable to pick coordinates, so silently eaten
away.
