Add Python 3.12 support (#1676)

* Add Python 3.12 support tag

* Bump nanobind to latest stable v1.6.2 tag

* Add PyPI trusted publishing to GitHub workflow, add Python 3.12 wheel builds

Trusted publishing has been available since v1.8.0 of the pypa-publish
action. It enables password-less authentication and wheel uploads from
the wheel upload job.

`cibuildwheel` was bumped to v2.16.2 to allow Python 3.12 wheel builds.

More info on trusted publishing:
https://github.com/marketplace/actions/pypi-publish#trusted-publishing

The Windows distribution was reverted to `latest` in the OS matrix,
since the discovery problem of MSVC was fixed in a Bazel patch release.

* Bump nanobind to stable v1.7.0 tag
