Disable filtering out TensorFlow-internal frames in exception stack traces.

Raw TensorFlow stack traces involve many internal frames, which can be challenging to read through, while not being actionable for end users. By default, TensorFlow filters internal frames in most exceptions that it raises, to keep stack traces short, readable, and focused on what's actionable for end users (their own code).

Calling tf.debugging.disable_traceback_filtering disables this filtering mechanism, meaning that TensorFlow exceptions stack traces will include all frames, in particular TensorFlow-internal ones.

If you are debugging a TensorFlow-internal issue, you need to call tf.debugging.disable_traceback_filtering. To re-enable traceback filtering afterwards, you can call tf.debugging.enable_traceback_filtering().
