feat(wm): add noop cross-monitor-move-behaviour

This commit adds a new "NoOp" MoveBehaviour for users who don't want any
moves to happen across monitor boundaries. The
toggle-cross-monitor-move-behaviour will only toggle between Swap and
Insert, and will do nothing if NoOp is the selected MoveBehaviour.
