Check that annotation attribute values are concise when referencing something defined by an inner-type of the annotation

When the value of an annotation's attribute references something defined by an inner type of the annotation, the inner type should be imported and referenced directly rather than through the containing type.

Consider the following:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

The repetition of SpringBootTest in both the annotation itself and the value of one of its attributes is overly verbose. Instead, we prefer to import WebEnvironment and refer to it directly:

@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)

Check that annotation attribute values are concise

This needs some refinement. Switching from @Annotation.InnerType to InnerType results in an import of com.example.Annotation. If it's deprecated, this will cause a compiler warning as illustrated in Spring Boot 4.0.x (428963e02d171711e0ce25c01d2b3cc0da366ce9):

> Compilation failed; see the compiler output below.
  …/module/spring-boot-jackson2/src/test/java/org/springframework/boot/jackson2/NameAndAgeJsonKeyComponent.java:27: warning: [removal] JsonComponent in org.springframework.boot.jackson2 has been deprecated and marked for removal
