[#11720] DocDB: Use lightweight protobuf for sending Perform request.

Summary:
We use google protobuf for cummunicating between nodes or postgres and tserver.
Native protobuf implementation allocates a lot of memory while generating requests.
This diff switches Perform RPC to our lightweight protobuf implementation.
What uses arena for allocation and tries to avoid allocation as much as possible.
