DMPlexTransform: Allow for plex meshes that do not use standard ordering

DMPlexTransform assumed that the order of points would be cells->vertices->edges (in 2D).
Some cases, such as a DMForest converted to a DMPlex, might have cells->edges->vertices, which results
in points being incorrectly flagged as out-of-range. The new cell type order function has been updated to order cell types by the ordering in the DMPlex.

Added additional tests for DMForest->DMPlex during extrusion.
