[libc++][doc] Update paper status.

[Mordante]

Summary

Update the status with the approved papers and LWG-issues in the October 2021 plenary.

The status of in progress is correct, I already looked at it while working on P2216.

Feel free to put this as in progress if you'd like. I have a PR for it at https://reviews.llvm.org/D111197

In general we don't use In Progress for the official paper status only for subprojects for aligning the work.
But lets see which patch lands first and then make sure the second one sets the proper state for P2251.

We seem to be missing the LWG issues that were moved in the meeting. They are in http://wg21.link/p2450r0.

This is a dupe with the previous line.

Yeah let's just rebase @jloser 's patch on top of this one and mark the paper as complete.

[Mordante]

Addresses review comments.
Update the LWG issues.

[ldionne]

Thanks!

Ideally, we'd have a way to avoid duplicating issues in e.g. Cxx20Issues.csv and RangesIssues.csv by having some sort of tagging system, but csv isn't really the best tool for that.

As discussed on Discord I want to look at removing the duplication, but in a separate patch.
