gh-127330: Update for OpenSSL 3.4 by encukou · Pull Request #127331 · python/cpython

Also:
- Avoid the deprecated `datetime.datetime.utcnow()`
- Fix newline

This requires that the OpenSSL source tree is a Git checkout,
and that you have Git installed. Both should be fine for a tool
run manually by people who can change the tool.

… process (pythonGH-127331)

- Add `git describe` output to headers generated by `make_ssl_data.py`

  This info is more important than the date when the file was generated.
  It does mean that the tool now requires a Git checkout of OpenSSL,
  not for example a release tarball.

- Regenerate the older file to add the info.
  To the other older file, add a note about manual edits.

- Add notes on how to add a new OpenSSL version

- Add 3.4 error messages and multissl tests
