[Analysis API] fix IndexOutOfRangeException

Previously, the `KtFirUsualClassType.qualifiers` was empty for the local classes

The reason was a RawFirBuilder setting up a containingClassForLocalAttr
to the outer non-local class for the local class. It should be a null instead,
see the localClassType.kt as an example

^KT-55510 fixed
