This change adds entry-point annotations to methods and classes accessed by native code during engine tests. Currently, entry point annotations are not checked by the Dart VM when running in JIT mode, only in AOT mode. In order to also enforce entry point annotations in JIT mode, first tests in Flutter must be appropriately annotated to avoid roll failures.
