This adds a `#highest_allowed` method to `MacOSRequirement`, so we can easily identify the highest supported macOS version that a requirement allows, if any. This can be used when producing a minimal set of supported macOS versions that meet requirements in `UsesOnSystem.macos_requirements`. One of the intended use cases for this is to identify which macOS versions we could simulate to work with all variations of a cask that uses macOS on_system blocks.
