Hello,

Here's a patchset that adds support for Python 3.13 freethreading
version.

Originally, this was dev-lang/python:3.13[-gil]. However, since it is ABI-incompatible at extension level with the regular build of CPython,
upstream decided to split it into a separate /usr/lib/python3.13t
install tree, with its own .so suffix, wheel tag and so on. All things considered, it seems to make most sense to treat it separately in Gentoo
as well.

So for this, we do:

1. Introduce dev-lang/python-freethreading that installs
the freethreading version of CPython (:3.13t).

2. Introduce 'python3_13t' Python target for it.

Note that at this point freethreading support is limited. Some packages
do support it, others may work incidentally. Right now, the stable ABI
is not supported at all. Hopefully, this will be improved
in the future (and I really do hope we won't have to repeat this split
for Python 3.14). In any case, the extra advantage of splitting it
right now is that it permits us to test freethreading support separately
and explicitly mark packages that work with that.

Freethreading is considered experimental upstream. Unlike python3_13
target, python3_13t is not intended to be unmasked on stable. We are
also using a separate package name to avoid having to hack PV into
something like 3.13.0 + 3.13.0-r100, and to avoid having Portage insist
on installing the freethreading version, as it loves to proactively
upgrade stuff. In fact, perhaps we should consider splitting all slots
of Python into separate packages in the future.

That said, the current implementation is not nice for PYTHON_COMPAT:

PYTHON_COMPAT=( pypy3 python3_{10..13} python3_13t )

I'm still considering our options here, but I don't think there's any
really clean way of avoiding this.

Remove freethreading support from dev-lang/python in favor of a separate package. These two variations of Python are not ABI compatible and use separate installation trees.
