ENH: provide triSurfaceTools::validTri() method to reduce code duplication

Browse Source 
- identical code was present in surfaceCheck (original source),
  and isoSurface, isoSurfaceCell (copies).

- add in a MeshedSurface<face> variant as well, since this will likely
  be needed in the near future
