Introduce display specific all window drawn waiting (3/N)

This change modified the waitForAllWindowsDrawn API to wait for
windows on a specific display. INVALID_DISPLAY indicates to wait on all
visible windows on all displays.

To achieve that, it introduced a callback HashMap in WMS and a window
container as a parameter in the waiting related messages. The actual
window registration is done by WindowContainere
