Allow skipping inference when running evaluation.
* `inference_on_dataset_with_checkpointing` works similar to `inference_on_dataset` in d2 but allows skipping the inference step if the evaluator has cached the results.
* If the evaluator has a function `could_skip_process` and returns True, inference will be skipped and only `evaluator. reset()` and `evaluator.evaluate()` are called.
