feat!: bump Firebase iOS SDK to 13.0.0

BREAKING CHANGE: Swift Package Manager builds now use Firebase Apple SDK 13 and require macOS 11. firebase_ml_model_downloader is unavailable with Swift Package Manager because Firebase Apple SDK 13 no longer ships FirebaseMLModelDownloader; its method calls return an `unimplemented` error. CocoaPods builds stay on Firebase Apple SDK 12.19.0 and macOS 10.15, and are unaffected.
