workflows: macos: Use matrix for building Apple Silicon artefacts

[cosmo0920]

GitHub now published hosted runners which are based on M1 macOS: https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories

To use them and continue to use Intel mac runners, we need to specify them with build matrix and set up with macos-12 and macos-14. Now, macos-latest is pointed in macos-14. So, we need to specify macos-12 or macos-13 explicitly to create Intel Mac artefacts.
