Consistently support `@Autowired` as a meta-annotation

[sbrannen]

Overview

The findAutowiredAnnotation() method in AutowiredAnnotationBeanPostProcessor fully supports finding @Autowired as a meta-annotation; however, the isRequired() method in QualifierAnnotationAutowireCandidateResolver only finds @Autowired as a "directly present" annotation without any support for meta-annotations.

For consistency, and to avoid bugs, we should always support @Autowired as a meta-annotation.
