[Task] Add missing methods from models/Element/AbstractElement.php

[martineiber]

Some public methods have been added here
https://github.com/pimcore/pimcore/pull/18444/files

• setGetInheritedProperties()
• getGetInheritedProperties()

Currently they are just excluded from the Tests since it is a BC-Break when we add them to the contract interface.
