Richard Smith a45dc42d82 Store an InterfaceId and a SpecificId in AssociatedEntityType. (#5252)
Instead of storing a `TypeId` that always refer to a facet type that
always contains exactly a single interface, store the interface
directly.

Also improve stringification of `LookupImplWitness` and witness access
into it, switching to using newly-added functionality for stringifying
specific interfaces.
