Add support for detecting free-threaded Python on Windows
This does a couple of things:
1. Scrape the `Py_GIL_DISABLED` sysconfig var, which is the best way as of today
to determine whether the target interpreter was built with `--disable-gil`
2. link against the correct libpython
3. On Windows, work around a known issue in the python.org installer with a
missing define in `pyconfig.h`, which the CPython devs have said is unlikely
to be fixed since headers are shared between the regular and free-threaded
builds in a single NSIS installer.
