Use google.golang.org/protobuf messages in typed events

[aaronc]

We can do a type switch in TypedEventToEvent to see if we have a new proto.Message. Then we can use the protoreflect.Message.Range method to convert the event to an ABCI event rather than marshaling to JSON in the middle. This should be more efficient than the current method and also allow us to store unquoted strings in attribute values (rather than what happens now with JSON).

Probably ParseTypedEvent should decode to a new proto.Message if one exists.

[aaronc]

It we do this correctly, it should allow us to resolve any performance issues associated with JSON marshaling for typed events. We may even want to consider deprecating gogo support because of this.

The key thing is being able to iterate over the fields in a deterministic way which protoreflect.Message.Range is not guaranteed to do. Either we can sort fields, or have an extension interface that pulsar exposes with a DeterministicRange method.

Would rather sort the fields rather than rely on Pulsar.

I think we can support both options

i think if someone is sending events to tendermint they should not assume it doesnt come with a little overhead

closing as we decided to deal with one proto type for now in the state machine
