Fix vtkGeometryFilter and vtkTableBasedClipDataSet
vtkGeometryFilter now 1) properly handles distributed structured cases, 2) has the correct faces orientation, and 3) solves a thread-safety issue that caused the update of progress by many threads.
vtkTableBasedClipDataSet now 1) does not promote conversion of arrays to float/double (same as vtkDataSetAttributes), 2) and supports again GenerateClipScalars.
