This makes convert more consistent, it always makes a FacetAccessType for a facet value, rather than only doing so after lookup returns. The intention for this is that FacetAccessType will evaluate to SymbolicBindingType in the future, so this will expose that constant value to impl lookup instead of the original facet value, which will avoid impl lookup having to deal with `.Self` or `BindSymbolicName` specifically.
