Cross reference annotation search APIs in Javadoc #34421
Description
Spring Framework provides several APIs for performing annotation searches that have grown organically over the years, and it's not always clear to users and integrators which API to use for a given use case.
To address that, we should cross reference the annotation search APIs in MergedAnnotations, AnnotatedElementUtils, AnnotationUtils, and TestContextAnnotationUtils and provide minimal guidance for when to use which.
