When the use_legacy_prediction_loop parameter is used , Trainer.predict will raise an error AttributeError: 'PredictionOutput' object has no attribute 'num_samples'

What does this PR do?

  1. Use EvalLoopOutput instead of original PredictionOutput of self.prediction_loop, this makes the return formats of self.prediction_loop same as self.evaluation_loop.
