Callers can use this to save themselves an isinstance() test. The only remaining user of this convenience feature is .lookup_type(). But we don't actually save anything anymore there: we still the isinstance() to help mypy over the hump. Drop the .lookup_entity() argument, and adjust .lookup_type().
