Update Web module's serializers
Some updates from trame's patches to this module. I'm hoping this can land in the 9.2.3 release (cc @ben.boeckel)
Patches coming from: https://github.com/Kitware/trame-vtk/blob/master/trame_vtk/modules/vtk/addon_serializer.py
FYI, @sebastien.jourdain
I also changed the debug print statements in this module to use debug logging, which will resolve https://github.com/Kitware/trame/issues/167
I did test these changes locally and all seems okay
There are also some print statements in the following files that I think may need to be changed:
Web/Python/vtkmodules/web/dataset_builder.pyWeb/Python/vtkmodules/web/camera.py
Backport: paraview/release
Backport: release
