[Noir Contracts] Provide a way for a user to validate the hard-coded function selectors of a contract interface

[iAmMichaelConnor]

If we continue with our current approach for generating contract interfaces, a developer shouldn't blindly trust these opaque hex function selectors. We probably need a way for a user (dev) who uses one of these contract interfaces to validate the correctness of the hex function selector.

Maybe we could include the selector in the generated ABIs? Or add a CLI command that outputs the list of functions and their selectors given a contract?

Issue began here: #1487 (comment)

@iAmMichaelConnor is this sufficiently fixed by #2686

I think it does, yeah.
