Implement getField CEL function (#90)
I'm proposing this as an eventual replacement (before 1.0) of our hack around the fact that the in identifier is reserved in CEL. We need this for protovalidate-cc especially so we can start removing our cel-cpp patches. Protovalidate PR: bufbuild/protovalidate#352
