Centralize more of distributed planning into CreateDistributedPlan(). 

The name CreatePhysicalPlan() hasn't been accurate for a while, and
the split of work between multi_planner() and CreatePhysicalPlan()
doesn't seem perfect.  So rename to CreateDistributedPlan() and move a
bit more logic in there.
