When iterating over all Platforms looking for the best one, on a Mac the Simulator platforms (iOS, tvOS, watchOS) will first find their SDK directory by calling xcrun, then decide if they should activate or not. When that SDK is absent, the call to xcrun to find it can be very slow. This patch delays that directory search until we know we're activating this platform, so non-simulator environments don't pay a perf cost ever time they go through the list of platforms.
