ci: build (and use) wheel for all supported version

We test wheel building for all supported version and use them where applicable

The usage is more verbose than I wish because .gitlab-ci is not that great.

    This tests for edge cases in url.URL's parsing algorithm. Most of
    these aren't useful for documentation purposes, so they aren't
    part of the class's doc tests.

    Query strings and fragments:

    >>> url(b'http://host/a?b#c')
    <url scheme: 'http', host: 'host', path: 'a', query: 'b', fragment: 'c'>
    >>> url(b'http://host/a?')
