ci: use GitHub-hosted macOS runners (#1470)

The GitHub-hosted macOS runners have been updated to include arm64 M1 options now. This PR switches our workflows to use them instead of the self-hosted runner. There is more availability for these runners and they run just about as fast, if not faster when accounting for parallel jobs. The `release` workflow was updated to change `macos-latest` to `macos-14` to be specific about the version in the matrix and allow for adding additional versions in the future.
