feat(filtersets): Add ContentTypeFilter to enhance filtering

Introduce `ContentTypeFilter` across several filtersets, including
`object_type`, `related_object_type`, `assigned_object_type`, and
`parent_object_type`. This improvement enhances filtering specificity
and aligns with existing usability standards.

Closes #20554
