plex: Correct Mat preallocation for isoperiodic grids

Requires:
- Using isoperiodic SF instead of the (purely topological) pointSF
- Force the use of the isoperiodic SF even if in serial
- Handle the case of an isoperiodic SF leaf-root pair a) being on the
same rank and b) both being present in the same adjancency
