setup/pyproject/makefile/tools/lint-and-test: Setup with pyproject.toml.

This transfers details from setup.py to equivalent ones in pyproject.toml,
and similarly removes or substitutes references to these files. The
previous setup.py file is removed.

Note: This introduces 3 other changes from the previous state:
* Building packages no longer removes the top title line shown on GitHub
* The `zip_safe` property is detected automatically by `setuptools`
* The types-setuptools package is included for type-checking

This also adds a note to the making-a-new-release doc, since while it was
previously out of date, setup.py will now be absent completely.
