Summary Python 3.13 support

With Python 3.13 in a venv, with setuptools installed (see bug 261113), we potentially surprisingly almost manage to work: We get: No archives for zope-interface-7.0.1 found No archives for MarkupSafe-2.1.5 found Both of these are modules where we require wheels, and neither have Python 3.13 wheels for macOS: see https://pypi.org/project/zope.interface/7.0.1/#files and https://pypi.org/project/MarkupSafe/2.1.5/#files That said, I can't see anything that requires zope-interface-7.0.1, though MarkupSafe-2.1.5 is required by jinja2 which we use in a couple of places. Perhaps surprisingly, all the webkitpy tests do appear to pass on Python 3.13, but we get yet more deprecation warnings.

Running more than just webkitpy, one discovers webkitflaskpy depends on hiredis-3.0.0 and lupa-2.2, neither of which have 3.13 wheels. But again, with them installed from source, we do actually pass all tests on Python 3.13.

So I think the main thing necessary for 3.13 support is upgrading pyfakefs to avoid https://github.com/pytest-dev/pyfakefs/issues/1017, and then we're gonna need to bump versions of the other dependencies or allow them to install (compile) from source.

Oh, and I forgot to mention "upgrading cffi", which is also necessary.
