Python wheels for 3.12

[NatanSlvdr]

In the 2.0.10 release, some commits are about building for python 3.12, but there are no wheels on PyPi.

Is it normal ?

The github workflow for building and publishing the wheel has not been working for a while.
I triggered a build for 2.0.10 here: https://github.com/arvidn/libtorrent/actions/runs/8579717727

Hi, it seems to have failed

It seem that there is an issue with the cibuildwheel action on the 2.0.10 release.
@arvidn you have pushed some changes to it only in 4ef2211 (which still fail on windows)

I tried to reconstruct the action run failure. I think what is happening is this (matching the log output):

1. The pypa/cibuildwheel@v2.12.3 is used (see here).
2. The default value of '' is used for the only input of the cibuildwheel action (see here).
3. Specifically for Windows, --only '"${{ inputs.only }}"' is used, which evaluates to --only '""' (see here).
4. The cibuildwheel application then parses the only command-line value as "", i.e., not empty (see here).
5. The cibuildwheel application tries to match "" to a known platform, which fails and causes the log statement Invalid --only='""', must be a build selector with a known platform (see here).

From the linked source code of (4), it seems that the only way out of this situation is to omit the argument only (to the application). However, this seems impossible due to the forced double-quotes of (3) in the pypa/cibuildwheel@v2.12.3 action. Thankfully, this seems to be recently fixed and it should just be a matter of switching to pypa/cibuildwheel@v2.17.0.

I hope that helps resolve this issue.
