[3.14] gh-132339: Add support for OpenSSL 3.5 (GH-137720) (#137747)

* Add OpenSSL 3.5.2 definitions to Modules/_ssl_data_35.h (moved from Modules/_ssl_data_34.h)

* Demote OpenSSL 3.1 to "old", remove it from CI

* Update all OpenSSL versions to latest patchlevel in CI config and multissltests defaults

* Add OpenSSL 3.5.2 to CI configuration and multissltests default list

* Fix a typo in the argument parser description of multissltests.py
(cherry picked from commit 7a703c8f1942c8bd07943458962f6e59d2892757)
