Prior to this commit, all clients of
ControllerAdviceBean.findAnnotatedBeans() sorted the returned list
manually. In addition, clients within the core Spring Framework
unnecessarily used AnnotationAwareOrderComparator instead of
OrderComparator to sort the list.

This commit presorts the ControllerAdviceBean list using OrderComparator
directly within ControllerAdviceBean.findAnnotatedBeans().

Closes gh-23188
