Summary0004205: Scripting: Add first-class support for "factory" method
Description

As described in [1], reference count associated with the object returned by method like "GetNodesByClass" or "CreateNodeByClass" has to be explicitly decremented when used from python.

The good news is that a Merge Request is currently being reviewed to allow these method to be marked as factory. Simply prepending these function declaration with VTK_NEWINSTANCE will teach the wrapped what to do.

See https://gitlab.kitware.com/vtk/vtk/merge_requests/1535

While the feature is now available in VTK, I am re-targeting to keep track of the fact we need to mark Slicer factory methods.

It would need a lot of changes in modules and extensions, so work on this in Slicer5.
