    x11/window: Ensure we send a ConfigureNotify to just mapped windows
    
    When managing a non-OR window we're required by the ICCCM to behave as
    if we received a ConfigureRequest which means that we must generate a
    synthetic ConfigureNotify even if the window isn't moved or resized
    from its current (initial) geometry.
    
    During MetaWindow's x11/wayland split a slight behavior change for x11
    windows crept in. Before the code split, MetaWindow->rect was
    initialized with the X window's geometry, but now we're not
    initializing MetaWindowX11Private->client_rect which causes the checks
    for whether it's necessary to move/resize the window in
    meta_window_x11_move_resize_internal() to tell us that we do need to
    move/resize which means we do an XConfigureWindow() call and don't
    send the sythetic ConfigureNotify. But since the X window isn't really
    moving, the XConfigureWindow() call doesn't cause the X server to
    generate a ConfigureNotify which breaks some clients such as Java's
    AWT.
    
    We can fix this by setting MetaWindowX11Privatew->client_rect for both
    OR and non-OR windows. We can set buffer_rect for non-OR windows as
    well to simplify the code since it will be assigned the correct value
    in meta_window_x11_move_resize_internal() .
