Replace vc_util and canister_sig_util with external crates (#2584)

The canister_sig_util crate has been replace by the properly published
`ic-canister-sig-creation` crate. The `vc_util` crate has been moved to
the verifiable credentials SDK repo.
This PR removes a lot of duplication and streamlines the II repo massively.
Also, having more external crates should improve caching in the II CI
infrastructure.
