    gtk4: use the FixedContainer overlay for mouse events after all
    
    Remove gtk_widget_set_can_target on the overlay so that when we put
    native gtk widgets into the overlay they get events and can be
    interacted with.
    
    The DrawingArea is 'underneath' the overlay. So just move the mouse
    event handlers to the overlay itself so we can still appear to interact
    with the DrawingArea.
