Fix corner cases where _NET_WM_FRAME_DRAWN might be missed
The WM spec requires _NET_WM_FRAME_DRAWN to *always* be sent when there is an appropriate update to the sync counter value. We were potentially missing _NET_WM_FRAME_DRAWN when an application did a spontaneous update during an interactive resize and during effects. Refactor the code to always send _NET_WM_FRAME_DRAWN, even when a window is frozen. https://bugzilla.gnome.org/show_bug.cgi?id=693833
