x11window: Send ConfigureNotify events when moving windows

This removes the optimization that sends only one ConfigureNotify event after moving is completed.
However, other windows may depend on ConfigureNotify events to adjust their position in a timely
manner. For example, the shadow window surrounding the main login window of WeChat on Wine.
