4609: [Access] Update default grpc max message size to 1GiB r=peterargue a=peterargue

Closes: #4596

The amount of data returned from some Access API requests has increased over time, resulting in response size errors on Access and Execution nodes. While the max message size is configurable via CLI flags, this PR updates the default to be well above the current largest messages.
