Add options to onnxruntime_perf_runner to externalize weights (#26441) ### Description Allow the user to externalize weights, set the minimum weight threshold, and save pre-packs when saving an optimized model. ### Motivation and Context Add several options that make the tool more useful. Some models fail to optimize because they are too large. Externalizing initializers makes this possible.
