Helpers to querying raw state outside contracts

[Kayanski]

This PR aims at adding a simple helper to query raw state from outside contracts. Types are derived automatically.

You can use the following syntax :

const TEST_ITEM: Item<TestItem> = Item::new("test-item");
const TEST_MAP: Map<String, TestItem> = Map::new("test-map");

let contract = Contract::new(chain);
contract.item_query(TEST_ITEM);
contract.map_query(MAP_ITEM, map_key);

Do you think we should use this instead :

TEST_ITEM.cw_orch_query(&contract)?;
MAP_ITEM.cw_orch_query(&contract, map_key)?;
