Set persistent_workers and pin_memory as True

[eunwoosh]

Summary

Set persistent_workers and pin_memory as True in all tasks, which can decrease data loader time.
When training with persistent_workers in nncf, nncf saves dataloaders in cfg. It makes an error when deepcopy cfg in train_model function of each tasks because datalaoder with persistent_workers aren't pickleable.
So, I set persistent_workers as False in nncf.
