Subject: [PATCH] workflows: use macos-14 runner.

- Use `macos-14` instead of `macos-13` most of the time.
- For `tests` and `test default formula` builds: run on both
  macOS 13 x86_64 and macOS 14 arm64
- Pretend `macos-14` is a self-hosted runner until a new version of
  `actionlint` is released which doesn't error on `macos-14`.
