In this PR we improve the decorated private method check in decorator transform. It now reuses the private name visitor factory from the class features plugin, which can handle the shadowed private name usage.
We also move the check after the decorator transform so that if the decorated method gets updated in its own function body, we can still detect such error.
This PR can be reviewed by commits.
