dix/window: Use ConfigureWindow instead of MoveWindow

The screensaver can regularly move its window to random offsets. It should
use the ConfigureWindow function instead of calling the Screen's MoveWindow
directly. Some MoveWindow implementations, such as compMoveWindow, rely on
Screen's ConfigNotify being called first as it happens in ConfigureWindow.
