Consolidate vendored packages in the setuptools package.
Now that the vendoring doesn't depend on importing the setuptools package, it's safe for pkg_resources to import _from_ there without actually importing setuptools.

Rewrite marker evaluation to address two type check failures.
1. The early `req.marker` works around a limitation that mypy can't detect that `not req.marker` is evaluated prior to entering the generator. 2. The `None` → `""` honors the type spec (`dict-item`) and avoids relying on the [deprecated code path](https://github.com/pypa/packaging/blob/793ee28b4c70886e8de5731e24e444388916b3ee/src/packaging/markers.py#L322-L323) allowing `None`.
