cranelift-faerie: upgrade to faerie 0.15.0, fix error reporting

the `FaerieProduct` exposes faerie-specific types, so we can give
the `faerie::ArtifactError` on those methods.

`ModuleError::Backend` now expects an `anyhow::Error`, so we change
a .to_string into .into() and retain better error information.
