This change removes uses of toString transformer from Flutter engine. The transformer is already wired up in Dart SDK: front-end server from Dart SDK supports --delete-tostring-package-uri option. After this change only the integration test is left in the Flutter engine to make sure dart:ui is properly transformed. dart-lang/sdk#46022
