[Debt] Separate non-Cosmos logic from Cosmos folder/proto

[optout21]

Currently Cosmos proto/folder contain some chain-specific proto files and logic, for Stargate (protobuf serialization) case:

• Terra WASM messages
• Thorchain send (pending #2092)

This includes:

• chain-specific message within the Cosmos.proto file
• internal protobuf within Cosmos/Protobuf folder, such as terra_wasm_v1beta1_tx.proto.
• Specific conversion logic in ProtobufSerialization::convertMessage().

It would be good to separate these non-Cosmos, chain specific dependencies to their own folder (Terra, ...). However, this is not easy to do without much code duplication, as a big part is reused from Cosmos. Moving out messages to own proto file should be done without duplicating all Cosmos proto part. Cosmos signgin and ProtobufSerialization logic should be made extensible, with convert logic moved out in chain-specific parts, without duplicating the whole Cosmos signing logic (this would require changing the global/static methods to class members, with virtual overridable convert).
