requested to merge mwestphal/paraview:fix_field_data_domain_default_backport into release
vtkSMFieldDataDomain::ComputeDefaultValues was faulty in its logic interpreting enum values as indices.
This was working by chance on classic point/cell/field dataset but not working at all with other datasets.
This fixes it by considering the default_values as an enum value, eg vtkDataObject::FIELD or vtkDataObject::POINT as everywhere else in vtkSMFieldDataDomain.
Backport of !6241 (merged)
