Restrict coincident target updates to M3 constant laser only.

Browse source 
- Restrict M3 forced updates when there is a motion block with a
coincident target. Force syncing of the spindle state can lead to some
pauses during a job that has coincident targets. That’s not
particularly desirable. This ensures M4 dynamic mode is not effected by
this force-sync.
