Support for signing wasm/MsgInstantiateContract transactions

[enriquesouza]

Summary

This PR adds support for signing CosmWasm MsgInstantiateContract transactions on Cosmos SDK–based chains.

Changes

• Added protobuf message: cosmwasm.wasm.v1.MsgInstantiateContract
• Implemented message struct and encoder: wasm_message_instantiate_contract.rs
• Integrated support into Cosmos transaction builder
• Added test coverage with real data: sign_wasm_contract.rs

Notes

• This supports CosmWasm contracts such as those used by Thorchain or Kujira.
• Test vectors are based on actual chain data and signatures verified against broadcasted transactions.

Tests

• The test is covered successfully and broadcasted to blockchain

Previous PR closed

• It was closed because after compiling the C++ it included hundreds of .make files and after trying to remove them it rebased and added 98 files that were not mine.

Thanks @enriquesouza but it seems that we now have a minor clippy warning. Could you please take a look at that as well?
