cli: allow dynamic contract hash for contract bindings

[AliceInHunterland]

Close #3007

[AnnaShaleva]

I would like to ensure that generated wrapper with dynamic hash is valid. Can we create a test (using neotest): generate wrapper with dynamic hash for some test contract (we may reuse one of the already existing test contracts), create a tiny helper contract that uses this wrapper inside some simple API (that creates an instance of Contract and calls its method):

func CallWrapper(h interop.Hash160) int {
    ...
}

Then deploy both contract and helper, then call helper and check that everything works as expected.
