Proposal messages are missing `cosmos_proto.implements_interface` option

[pyramation]

Summary

related to cosmos-sdk issue here

in ADR 019 it states

In .proto files:
fields which accept interfaces should be annotated with cosmos_proto.accepts_interface using the same full-qualified name passed as protoName to InterfaceRegistry.RegisterInterface
interface implementations should be annotated with cosmos_proto.implements_interface using the same full-qualified name passed as protoName to InterfaceRegistry.RegisterInterface

In the future, protoName, cosmos_proto.accepts_interface, cosmos_proto.implements_interface may be used via code generation, reflection &/or static linting.

We're doing codegen, and we're missing many of the cosmos_proto.implements_interface: hyperweb-io/telescope#118 (comment)

If we can add these into the protos, it would help the codegen flow to make client-side serialization better.
