Add zip_longest in the cirq google sweep proto

[BichengYing]

Looks like the generated proto.py format is different. how can i I guarantee they are same? (I have checked the version of grpcio-tools and mypy-protobuf @pavoljuhas)

I see the same error when running checks/protos-up-to-date for your PR.
What are the Python, grpcio-tools and mypy-protobuf versions on your side?

For me it is

Python 3.10.14
grpcio-tools   1.59.5
mypy-protobuf  3.6.0

If you have different versions, please run pip install -r dev_tools/requirements/deps/protos.txt in your virtual environment. Also make sure to use the dev_tools/build-protos.sh script to refresh the *_pb2.py files.

LGTM with a tiny suggestion. Please re-generate the run_context_pb2.py file to unblock the CI.
