Build wheels for Python 3.12

[phillipuniverse]

Long story short

Publishing CPython 3.12 wheels to PyPI would help other projects that use multidict and are working on their own CPython 3.12 support and distribution.

Also this issue is effectively copied from #778

Expected behaviour

pip is able to install multidict wheels from PyPI with CPython 3.12.

Actual behaviour

The sdist is downloaded instead such that building is required.

Steps to reproduce

Look on PyPI and note there are no cp312 wheels available.

Your environment

CPython 3.12

Yes, this is also a requirement of sigstore, and is the reason why installing sigstore currently fails on Windows for example, with a fresh installation of Python 3.12 - so the Python 3.12 installation package cannot be verified with sigstore at the moment.

Any ETA for this?

[pythonweb2]

The blackd server is dependent on this project and cannot be built on windows. It would be great if python 3.12 wheels could be hosted on PyPI soon.

It seems that 3.12 is not supported yet: #877, not just that the wheels have been forgotten.

Please create wheels. on windows the workaround is to install the 6.72GB visual studio build tools for c++.

I'll get to it once frozenlist is ready.

Since I have tons of windows and really hate to add the visual studio bloat, I added the whee here:
pip install https://github.com/fenchu/python312-wheels/raw/main/multidict/multidict-6.0.4-cp312-cp312-win_amd64.whl

I'll get to it once frozenlist is ready.

It seems the PR for python 3.12 on frozenlist had been merged now. Multidict is the new blocking point for many packages for python 3.12

All necessary pull requests are there. anaconda did workaround temporarly to not be stopped. At same time I see workloads in the cloud in Python-3.8, on premise load on python-3.11, and the python-3.13 twisters of multi-interpreters, jit, and free threads are coming... how can our benevolant giants withstand this ?
