* Pull SDK lookup code into a new `locator` class, which caches its results * SDKLocator only queries one SDK location, not all SDK locations * Build a map of all installed SDKs inside that location, instead of just the requested SDK * Ask xcrun for --show-sdk-platform-path first so that all SDKs can be found, instead of asking xcodebuild for a specific SDK * Add a new `SDK` class, which tracks the version and the prefix; add a new `MacOS.sdk` method which returns an `SDK` instance instead of a bare path; MacOS.sdk_path still returns a bare path
