[gtk+/wip/matthiasc/kill-event-signals: 67/81] Add x/y to GtkEventControllerMotion::enter



commit d2815d193e64db848db4e815b92bb86181d0cff2
Author: Matthias Clasen <mclasen redhat com>

    Add x/y to GtkEventControllerMotion::enter
    
    We have this information available in enter events,
    and having it in the controller signal as well makes
    porting easier.
    
    Update existing users.
