Fix simple subsurf on wire edges
Subsurf on wire edges gave smooth results even if set to simple
subdiv. Added a field to the CCG meshIFC to flag simple subdivision,
then when syncing vertices simply skip moving vertices if in
simple-subdiv mode.
This change affects two places, the level-1 build in sync and the
subdivision up to other levels.
Fixes bug [#32268] Simple Subsurf Modifier gives unexpected results on
edges without faces
