16920: Mark vtkPainterCommunicator as not wrappable
The header for vtkPainterCommunicator was not listed in CMakeLists.txt, and since the wrappers had no knowledge of it, the wrappers assumed that it was a vtkObjectBase-derived class from a different module. Hence any methods that accepted a "vtkPainterCommunicator *" parameter were wrapped incorrectly and would segfault when called.
Closes #16920 (closed)
