gh-119664: Remove deprecated co_lnotab

[picnixz]

This removes the deprecated code.co_lnotab attribute.

I am opening a (perhaps incomplete) PR because there are some things I am unusure of, such as:

• is it correct to entirely remove the block in clinic.test.c?
• there are some places where lnotab is referred so I changed them; should it be addressed separately?
• should we keep the PyCode_Optimize function?

I know that the doc and the news are not yet updated because I am waiting for feedback.

• Issue: Remove deprecated code.co_lnotab #119664

I think this needs more discussion. See my comment on the issue.

A Python core developer has requested some changes be made to your pull request before we can consider merging it. If you could please address their requests along with any other requests in other reviews from core developers that would be appreciated.

Once you have made the requested changes, please leave a comment on this pull request containing the phrase I have made the requested changes; please review again. I will then notify any core developers who have left a review that you're ready for them to take another look at this pull request.

Sure! I'll mark the PR as a draft to avoid possible noise for now.

Since it was decided not to do the removal now, I'm closing the PR.
