Bug description:
  SRU: update gcc-12 to the final gcc 12.3.0 release

  update 23.04, 22.10 and 22.04 LTS to the final gcc-12 12.3.0 release.
  The releases ship with a GCC 12 pre-release version (built from the
  gcc-12 branch). Update that one to the final 12.3.0 release.

  The GCC testsuite itself doesn't show regressions.

  A test-rebuild of lunar/main with updated Python and GCC packages was
  done to check for regressions:

  the first one is the reference test rebuild, the second one the
  rebuild using updated binutils, GCC and python packages.

  There are two regressions:

   - libcupsfilters, addressed in SRU LP: #2025150 (symbols file)
