xwayland: Stop using event address as event_id

Browse source 
Nothing should be relying on this anymore, so use a counter like other
places in the tree instead. This ensures that the event_id doesn't get
cast back into a pointer again in future, and also may be slightly less
confusing in cases where calloc reuses an address as debug logs would
show the same event_id for those but now they will be distinct.
