CI: Migrate macOS integration tests to macOS 12, drop Python 2.7 jobs

macOS 11 is not longer an available runner on Azure Devops. The minimum is now
macOS 12. This runner does not have Python 2.7 installed, so running them
would require a custom install - which I'm declaring too much effort for too
little gain.
