Previously, @ConfigurationProperties was not annotated with @Indexed.
This meant that @ConfigurationPropertiesScan would not be able to
find them when the underlying
ClassPathScanningCandidateComponentProvider is using a
CandidateComponentsIndex.

This commit annotated @ConfigurationProperties with @Indexed so that
they can be found by index-based scanning.

Previously, users of the components.index could not use the index in
scenario where Spring Boot needs to locate the SpringBootConfiguration
to use to bootstrap the test context, as AnnotatedClassFinder scans
the classpath for that stereotype specifically and that requires a
dedicated entry for it.

This commit makes sure that a SpringBootConfiguration-annotated type has
a dedicated entry in the components index.
