Convert setup.cfg to pyproject.toml+.flake8

Convert to pyproject setuptools metadata.
The setup.py stub is left in place.

All tool configs are converted here as appropriate, including flake8
as `.flake8`.

Not all comments were preserved identically -- this was taken as an
opportunity to rewrite the comments in some cases.
