classes declaration:

fix: class of the same unqualified name in package inside module (see MultiFileTest.testClassOfTheSameNameInAnotherPackage)

We don't ever try to use meaningful var name for temp class declaration — we remember about incremental compilation  inline final class declaration don't generate scope function if we don't need it

failed and fixed test: fast fix Kt817 (we must investigate, actually, it seems dart ast bug — we must have ability to declare name in our scope without check the same name in the parent scope)

perfomance: delete ClassSortingUtils, we don't need it
