GdkWindowX11: Communicate gdk_frame_timings_get_slept_before() to the compositor
GdkWindowX11: Communicate gdk_frame_timings_get_slept_before() to the compositor

We want the compositor to do different things for frames where
"slept before" is TRUE. Communicate to the compositor that
frame is a no-delay frame (slept_before=FALSE) by ending the frame
by increasing the counter value by 1, and that the frame is a
normal frame (slept_before=TRUE) by increasing the counter value
by 3.
