window: Make default focus window on each workspace appear focused

Browse Source 
Makes workspace transitions in gnome-shell look more seamless, since
both outgoing and incoming workspace have focused windows.

This is only done for click focus mode, since it's not known which
window would be focused for the other modes.

Track the state and recompute it when it changes, to avoid redrawing
the windows needlessly.
