all: Replace "black" with "ruff format".

- Add config for [tool.ruff.format] to pyproject.toml.
- Update pre-commit to run both ruff and ruff-format (and only check C
  files when running codeformat.py)
- Update CI.
- Simplify codeformat.py to remove all the Python-specific logic (just run
  "ruff format" directly).

This work was funded through GitHub Sponsors.
