Martin Gräßlin e7019d9545 [xwayland] Add support for WL_SURFACE_ID
When XWayland associates a Wayland surface with an X window it
sends a WL_SURFACE_ID client message to the window manager.

KWin listens for this client message in Toplevel and provides it
as a member in Toplevel.

This requires KWin to actually start a Wayland server (and XWayland)
to make proper use of the information.
