When determining macOS requirements for a cask, we may need to reference requirements from related on_system blocks (e.g., `on_monterey :or_older`, `on_ventura`, `on_sonoma :or_newer`) when `depends_on macos` isn't adequate. Sometimes casks specify different `depends_on macos` values in macOS on_system blocks but that value is only set when the cask is loaded in an environment that satisfies the on_system block's requirements. There are other casks that contain macOS on_system blocks and use `depends_on macos` outside of the on_system blocks but it may only use the macOS version of the lowest on_system block (e.g., `>= :monterey`), which isn't sufficient if the cask's values vary based on macOS version. To be able to simulate macOS versions that meet the requirements of all the on_system blocks in a cask, we need to collect the macOS requirements in a way that doesn't require OS simulation. This is also something that's easy to do in on_system methods, so this adds a `macos_requirements` array to `UsesOnSystem`, containing `MacOSRequirement` objects created from the cask's macOS on_system block conditions.
