📝 Switch packaging metadata to use PEP 621

This patch migrated most related content to `pyproject.toml`
semi-automatically. The change was produced by using
`jaraco.develop.migrate-config` and `ini2toml`.

As a part of this change previously used for packaging configuration
`setup.cfg` and `setup.py` files have been removed.
`setup.py` hasn't been needed for quite a while but kept for backward
compatibility. We don't care about that anymore.
