feature: add support for py3-none-{platform} wheels

This extends the mechanism introduced in #1091 for `abi3` wheels.
Most of the mentions to `abi3` have been removed and replaced by a more generic `compatible_wheel`.
This allows to build a wheel `foo-0.1-py3-none-win_amd64.whl` only once and still test with every configured python.
