Enable building with Python 3

Port and fix up the patch used by the Debian project, see
https://salsa.debian.org/qt-kde-team/qt/qtwebengine/-/blob/0db62e47f0e2f5e4e00193b65da912fe0083088c/debian/patches/chromium-python3.patch which in turn was largely based on a patch from ArchLinux:
https://github.com/archlinux/svntogit-packages/blob/packages/qt5-webengine/trunk/qt5-webengine-chromium-python3.patch

Also contains upgrades of six and catapult to build with Python 3.11
and 3.12, plus some other additional fixes, e.g. for macOS builds.
