Extract metric_key_prefix during NotebookProgressCallback.on_evaluate (#11347)

* Pass metric_key_prefix as kwarg to on_evaluate

* Replace eval_loss with metric_key_prefix_loss

* Default to "eval" if metric_key_prefix not in kwargs

* Add kwargs to CallbackHandler.on_evaluate signature

* Revert "Add kwargs to CallbackHandler.on_evaluate signature"

This reverts commit 8d4c85ed512f558f7579d36771e907b3379947b7.

* Revert "Pass metric_key_prefix as kwarg to on_evaluate"

This reverts commit 7766bfe2718601230ae593d37b1317bd53cfc075.

* Extract metric_key_prefix from metrics
