core: Move Stack to StackTracker synchronization back to stack.c

Browse source 
We indirectly were relying on the MetaX11Stack for this. We strictly
need the _NET_CLIENT_LIST* property updates there, so move our own
internal synchronization to common code.

Fixes stacking changes of windows while there's no MetaX11Display.
