[gtk+/wip/carlosg/event-as-object: 834/844] gdk: Move additional code in gdk_event_new() to GdkEvent::constructed

[Carlos Garnacho <carlosg src gnome org>]

    gdk: Move additional code in gdk_event_new() to GdkEvent::constructed
    
    Now that the type is a construct only property, we can initialize the
    event fields properly here.
