Carlos Garnacho b151b1ba9e testsuite: Adjust gestures tests to gtk4 event delivery 
Events that get to gtk_main_do_event() have the toplevel GdkWindow
as event->any.window. Also, ensure that coordinates fall within
sensible places of the windows, since those might have shadows,
headerbars and whatnot on wayland.
