fix(ivy): NgOnChangesFeature no longer included in hello_world (#28187)

- Wraps the NgOnChangesFeature in a factory such that no side effects occur in the module root
- Adds comments to ngInherit property on feature definition interface to help guide others not to make the same mistake
- Updates compiler to generate the feature properly after the change to it being a factory
- Updates appropriate tests
