STYLE: Enable Pylint useless-parent-delegation warning (#49773)

* Enable Pylint useless-parent-delegation warning and remove superfluous overriding methods

* Remove annotations that caused errors.

Remove @skip_nested annotations that cause test failures and replace them with statements that suppress the useless-parent-delegation warning.

* Remove tests that can fall back to the base class

* Move a comment to ensure that pre-commit passes
