[Fun side project] Add on-chain cw-orch

[Kayanski]

This Pr aims at allowing users to interact with contract with the following syntax:

let query_result = Contract::load(deps, env).smart_query()?;
let execute_msg = Contract::load(deps, env).execute_msg()?;
let raw_query_result = Contract::load(deps, env).item_query(<Item>)?;

This uses the existing CwEnv structure and the derived Execute and QueryMsgs to work

Status

• Cw-orch-core is now compatible with wasm, it introduces a custom ContractWrapper structure (copied from cw-multi-test)
• Functional cousin contract test that leverages osmosis-test-tube and WASM !
• Add helpers to simplify the query and execution syntax

Checklist

• Changelog updated.
• Docs updated.
