Compare Kind references before checking log levels

Assuming reference comparisons are much quicker than checking
likely-nested logger levels, perform the former first.

Also, since the reference can match only one of the instances,
use "else if" to short-circuit the search.

Issue: SPR-10307
Added "beforeExistingAdvisors" flag to AbstractAdvisingBeanPostProcessor

Just AsyncAnnotationBeanPostProcessor switches "beforeExistingAdvisors" to "true" by default. So effectively, MethodValidation/PersistenceExceptionTranslationPostProcessor apply after existing advisors by default again, fixing the 3.1->3.2 regression.

Final preparations for 3.2.2
Document @Bean 'lite' mode vs @Configuration

Rework the reference documentation to better distinguish the differences
between @Bean methods used in @Comonent vs @Configuration classes. The
'Using the @Bean annotation' section now only covers concepts applicable
when using @Bean methods in @Configuration _or_ @Component classes.
Information only applicable to @Configuration classes has been moved to
a new  'Using the @Configuration annotation' section.

An additional sidebar section attempts to explain the differences
between the two approaches.
