add multi-owner cw-ownable with cosmwasm v2 (#1)

* move all logic to `OwnershipStore`. This way `cw-ownable` is still a singleton. But can be re-use e.g. by defining `CREATOR: OwnershipStore = OwnershipStore::new("creator")`

* cargo fmt

* cargo clippy --tests

* use api and storage (instead of DepsMut) for being less restrictive

* fix ownable

* remove unneccessary lifetime (clippy warning)
