Function to_graph_v1

Converts a Python entity into a TensorFlow graph. Also see: `tf.autograph.to_code`, `tf.function`. Unlike `tf.function`, `to_graph` is a low-level transpiler that converts Python code to TensorFlow graph code. It does not implement any caching, variable management or create any actual ops,
