ExtensionLoader override logic optimization

[EvenLjj]

Background

If one overrides ExtensionClass without adding an override label, it may result in the failure to load other ExtensionClasses of the same type. For instance, if you override the implementation of hessian2 without including an override tag, it will cause serializers like protobuf and json to not load.
