Code Review

This pull request refactors the optimizer and scheduler creation process by introducing an optimizer_callback and delegating tasks to HfTrainer static methods. It also adds a mechanism to filter out empty parameter groups during optimizer initialization. The review feedback points out that the create_optimizer_and_scheduler method should call the local create_optimizer to ensure the parameter group filtering is applied and suggests adding a null check for the optimizer for increased robustness.
