K2: add test for KT-56520, case (3), class literals

Again, both frontends here ignored classifiers from
explicit star imported scope (some.HashMap, java.util.HashMap)
because of their ambiguity. In case of K2, it works so due to logic
in BodyResolveComponents.resolveRootPartOfQualifier.
This function is called to resolve qualifier without receiver, in case
it's used as a receiver itself (::class counts as a selector equivalent).
