Problem

Currently, we have cases in Nargo where we hardcode the BACKEND_IDENTIFIER as acvm-backend-barretenberg; however, this doesn't work with alternative backends.

Happy Case

Backends should provide an identifier via a function. This could also possibly include their version or other information, such as field, features, etc.

Alternatives Considered

No response

Additional Context

Work has begun in noir-lang/acvm#196 and noir-lang/acvm-backend-barretenberg#189

Unsure if this is still relevant with the latest nargo backend works.

Happy to hear thoughts if any, cc @TomAFrench @kevaundray. Might close this as stale otherwise.

Yes, this is still relevant as artifacts are tailored for a particular backend.
