test_tools and test_venv fail because of pip: pypa/pip#11103

By default, make install fails on ensurepip, also because of pip.

Temporary workaround: ./configure --with-ensurepip=no: make install doesn't run ensurepip and so doesn't fail.

For now, this PR is a draft, and so I didn't write any documentation (no NEWS entry, no What's New in Python 3.12, etc.).

@erlend-aasland and I will have the last modules ported to Modules/Setup.stdlib very soon. We won't need distutils any more then. I recommend that we do not rename distutils and instead remove it once and for all.

See the issue #92584: peg_generator, c-analyzer tool and test_cppext still use distutils. I would prefer to not break them.

I modified test_cppext to build the C++ extension with setuptools. So far, so good: it works on all buildbots.

We can try a similar approach for test_peg_generator. Right now, test_peg_generator builds a library to make the test faster. I don't know how to port distutils code to setuptools.

How is it going? Is this work tracked somewhere?

For example, configure.ac mentions the array module, but setup.py still has code to build this extension. Is there a plan to remove the setup.py code, if the configure/Makefile code is enough? Or is there still a reason to keep the setup.py code?

I have created GH-93939

tl;dr every module that uses addext() can be built without distutils (except for a quirk in multiprocessing). Modules that use add() are not yet ported. I have an open PR for _ctypes.

It seems like most core devs don't want to keep distutils hidden in the stdlib, but want to directly remove it. So I close my PR. Remaining steps are tracked by other issues.
