Document @AliasFor support in AnnotatedTypeMetadata.getAnnotationAttributes()

Browse Source 
The Javadoc for getAnnotationAttributes() states that it supports
"attribute overrides on composed annotations"; however, it actually
supports @AliasFor in general, including attribute aliases within a
given annotation.

This commit updates the Javadoc and corresponding tests to reflect that.

Closes gh-31042
