IVGCVSW-7562 Implement DelegateTestInterpreter for classic delegate

 * Updated all tests to use new DelegateTestInterpreter.
 * Fixed some unit tests where the shape was incorrect.
 * Add file identifier to FlatBuffersBuilder, as it is required for
   validation when creating the model using new API.
