[AA] Add implementation for annotationApplicableTargets.

Adds implementation and tests for the new
KtClassOrObjectSymbol.annotationApplicableTargets property on
KtSymbolInfoProvider. This implementation delegates to the canonical
implementation in AnnotationChecker for FE1.0, and to the implementation
in FirAnnotationHelpers for FIR.

This change also includes direct tests for annotationApplicableTargets,
and a fix for FirClassLikeSymbol.getAllowedAnnotationTargets in
FirAnnotationHelpers.
