[caffe2] add a SerializationOptions field for the save operator (#53402) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/53402 Add an `options` field to the `Save` operator which accepts options for how to serialize different blobs. At the moment this simply allows controlling the existing `chunk_size` behavior, but in the future we can add other options, such as the ability to control compression settings or other serialization formats. ghstack-source-id: 123567034 Test Plan: Added a new test to `load_save_test.py` that passes in options and verifies that blobs were serialized with the expected number of chunks. buck test caffe2/caffe2:caffe2_test_cpu \ caffe2/caffe2/core:serialization_test \ caffe2/caffe2/python/operator_test:load_save_test Reviewed By: mraway Differential Revision: D26502577 fbshipit-source-id: 6e302e530bb96990517c2e35c505db7f14a56284
