Drop "send_event" boolean trap in X11Window::restackWindow()
The synthetic ConfigureNotify event is not sent when the stack mode is TopIf and BottomIf, i.e. the way the restackWindow() function handles the "send_event" argument is inconsistent.
And the window manager doesn't have to send a synthetic configure event when processing a _NET_RESTACK_WINDOW client message. It must do it only after handling a ConfigureRequest request, which the X11Window::configureRequestEvent() function already does.
So rather than fixing the handling of the "send_event" argument, this change removes that boolean trap instead.
