Provide default implementation for Annotations.getUseSiteTargetedAnnotations

After this commit, it's overridden only in AnnotationsImpl and
CompositeAnnotations.

Note that although FilteredAnnotations did have a non-trivial
implementation, that class was only used in circumstances where
annotations with use-site targets could not be of any use, so it's safe
to return empty list there now. One could argue that the new semantics
makes more sense: filter "standard" annotations, but don't touch those
with use-site targets because they are not applied to this element
directly, thus should likely not be affected by the filtering
