Fix how vtkDataSetTriangleFilter operates on wedges

Andrew Bauer requested to merge acbauer/vtk:tetrahedralize_wedge_fix into master

The vtkDataSetTriangleFilter assumed that the faces for 3D cells points in but for the wedge it points out so we shuffle the indices so that we don't get inverted tets. Note that this doesn't fix the issue for the Lagrange wedges for order 3 or higher.

Addresses #17282 (closed).
