This brings back two features mentioned in #135368

• __class__
• __dataclass_*__ features

Basically, the fix is rather obvious: we just set the proper fields.

__annotations__ has changed due to __annotate__ function, this is not our fault :)

I also have a revert PR ready, if this one is not good enough.

This PR should probably also get the backport 3.14 label.

Because of the way messes with authorship on merges, the CLA also needs to be signed for the noted address (I believe there's an option to tie it to a real address for CLA purposes, but this is an area I'm not that familiar with).

Just clicked on the link above and signed it again although I can even see the Legacy PSF Contributor Agreement there too. Oh well 🤷🏻‍♂️ Should be all good now.

Thanks @sobolevn for the PR, and @cjw296 for merging it 🌮🎉.. I'm working now to backport this PR to: 3.14.
🐍🍒⛏🤖

GH-135503 is a backport of this pull request to the 3.14 branch.

Did this need to go the 3.13 or earlier too?

Thank you! No, #124429 was never backported to 3.13, because it was a new feature.
