docs: Returns a dict to use as a filter for ordering operations
          containing the original ``Meta.order_with_respect_to`` value
          if provided. If the field is a Generic Relation, the dict
          returned contains names and values for looking up the
          relation's ``ct_field`` and ``fk_field`` attributes.
