Compare vtprotobuf + protobuf v2 with gogo protobuf

## Feature Request

### Describe your feature request related problem

Currently, gogo protobuf is no longer maintained anymore. Maybe someday, we need to replace it with golang protobuf but there is a performance issue compared with gogo.

### Describe the feature you'd like

From https://vitess.io/blog/2021-06-03-a-new-protobuf-generator-for-go, it has good performance and reduces a lot of CPU. Maybe we can use it in the future.
