[FIR] add missing resolve to isFinalClassConstructor

fix checking for intersection types in CheckIncompatibleTypeVariableUpperBounds

we need this resolve, because getEmptyIntersectionTypeKind under
the hood uses org.jetbrains.kotlin.resolve.checkers.EmptyIntersectionTypeChecker.computeEmptyIntersectionEmptiness
which uses computeByHavingCommonSubtype where we have
isFinalClassConstructor() call, so we need to resolve to STATUS phase
to get the correct modality
