[issue47143] Add types.copy_class() which updates closures

Lumír Balhar added the comment: Do you think it's a good idea to start a PR with a copy of the implementation from attrs for Python 3.11? We can then add tests for the new function and also some for dataclasses where this new function is needed and try to find all corner cases

[issue46404] 3.11a4: a small attrs regression
