[gtk+/wip/matthiasc/kill-event-signals: 84/126] Add x/y to GtkEventControllerMotion::enter

[Matthias Clasen <matthiasc src gnome org>]

commit 0888f743da06296077c60ee211bfd0a769bde5f1
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.
