Test suite type hint metadata fixturization x 2.

This commit is the next in a commit chain fundamentally refactoring our
test suite to leverage space- and time-efficient `pytest` session-scoped
fixtures rather than space- and time-inefficient ad-hoc machinery
previously defined by the `beartype_test.a00_unit.data.hint.pep`
subpackage, which @leycec requires to preserve personal sanity while
maintaining this lumbering juggernaut but nobody else particularly cares
about. It's best *not* to ask what this is about. Just know that our
test suite is demonstrably improving into something maintainable that
will no longer destroy @leycec's precious sanity points.
