    wayland: Don't emit premature configure events
    
    We should not emit configure events before we are realized - size
    changes at this point are not relevant.
    
    This gets rid of a mysterious emission of GdkSurface::size-changed
    with a size of 52x52, that is happening when GtkWindow sets the
    shadow_width before the window is mapped.
