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.
