Re-apply creation of python-3.12-base.

[smoser]

We tried python-3.12-default to provide symlinks python3 -> python3.12. That caused some problems as many things expected to get a /usr/bin/python3 (or /usr/bin/python) from installing 'python-3.12'.

The change here is to instead have python-3.12 provide /usr/bin/python3 as it did before, and depend on python-3.12-base for the primary files. python-3.12 and python-3.12-dev contain only symlinks.

The other changes here are a move of some files out of the runtime package and into -dev (usr/lib/python3.X/config-3.X-x86_64-linux-gnu). debian/ubuntu put these files in the -dev package.
