Instead of doing a lookup for the identified facet type from the impl's self+constraint, we can use `impl.interface` to get the specific interface being implemented by the impl declaration. This is already the specific interface returned from the identified facet type. And that means we no longer have to identify the self+constraint for imported impls. This is split out from https://github.com/carbon-language/carbon-lang/pull/7183#discussion_r3230571153
