Subject: [PATCH] treewide: add explicit format attribute for Python packages

If a Python package does not come with either `format` or `pyproject` we
consider it a setuptools build, that calls `setup.py` directly, which is
deprecated.

This change, as a first step, migrates a large chunk of these packages to
set setuptools as their explicit format

This is so we can unify the problem space for the next step of the
migration.
