python: update 3.11.5 -> 3.12.1

Drop distutils and smtpd modules from packaging, as both are gone in 3.12.

Rebase:
0020-configure.ac-setup.py-do-not-add-a-curses-include-pa.patch
(drop setup.py chunk as the file is gone)

Drop patches:
0001-Do-not-add-usr-lib-termcap-to-linker-flags-to-avoid-.patch
(setup.py gone, lib/termcap not mentioned anywhere else)

0001-Don-t-search-system-for-headers-libraries.patch
(setup.py gone, usr/lib64 not mentioned anywhere else)

0001-Makefile-do-not-compile-.pyc-in-parallel.patch
(replaced with COMPILEALL_OPTS= in EXTRA_OEMAKE)

0001-setup.py-Do-not-detect-multiarch-paths-when-cross-co.patch
(setup.py gone, add_multiarch_paths not mentioned anywhere else)

0017-setup.py-do-not-report-missing-dependencies-for-disa.patch
(has been superseded by Setup.local tweak in do_configure:prepend)

12-distutils-prefix-is-inside-staging-area.patch
(distutils has been removed upstream, so this old, unplesant hack can be finally dropped)

avoid_warning_about_tkinter.patch
(setup.py gone, tkinter detection logic performed in configure.ac)
