Fix a crash in `vtkPolyhedron::IsInside` when using multithread execution

Léon Victor requested to merge leon.victor/vtk:test_threadsafe_random into master

This is the continuation of !10733 (closed)

Relates #19182

Fix random crashes in ParaView, especially using the "Resample to Image" filter. This filter calls vtkMath::Random through the vtkPolyhedron::isInside method which is not thread safe.

This is a multi-threading concurrency issue, so hard to test in a reliable way unless you run a code X times hoping to crash. So I haven't written any test, but I can do so if required.
