Subject: [PATCH] GitHub Actions config update.

- Added clang-15 jobs.
- Added C++23 testing for gcc and clang on Linux.
- Updated clang version for UBSAN job.
- Removed clang-12 libc++ job - libc++ is now tested with clang-15.
- Updated Ubuntu version for clang jobs to avoid having to use external APT
  repository.
- Updated python package installation for compatibility with Ubuntu 22.04.
