CPython 3.12 wheels

[dlqqq]

(cc @kyamagu for visibility)

There are currently no CPython 3.12 wheels on PyPI (https://pypi.org/project/faiss-cpu/#files). This causes an error on platforms using CPython 3.12 which are unable to build faiss-cpu from source.

Can the contributors publish a new minor/patch release that includes CPython 3.12 for all platforms?

Example output, on an M1 Mac running CPython 3.12:

...

The current faiss release does not work for CPython 3.12 due to the deprecation of distutils module.

This PR implements fix for CPython 3.12+. The next release will include the update.

Any timeline for release? Even with just this PR many users would benefit.
