Merge #1488: ci: Add native macOS arm64 job

218f0cc ci: Add native macOS arm64 job (Hennadii Stepanov)

Pull request description:

  This PR starts using the [new](https://github.blog/changelog/2024-01-30-github-actions-introducing-the-new-m1-macos-runner-available-to-open-source/) M1 macOS runner.

  The alternative approach might be using a matrix, but it is not trivial to implement.
