This commits adds a checkstyle rule to not use List.of(), Set.of()
and Map.of(), preferring Collections.emptyList(), emptySet(), and
emptyMap() respectively.
It replaces usages of these methods across the codebase.

When running on Java 11 (where `@PostConstruct` is no longer part of
the JRE) and without a dependency on jakarta-annotation-api,
`@PostContruct` annotions are silently dropped. This leads to obscure and
hard-to-track down changes in the behaviour of our auto-configuration
as the `@PostConstruct`-annotated methods are not invoked.
To allow users to run on Java 11 without having jakarta-annotation-api
on the classpath, this commit removes use of `@PostConstruct` from main
code. A Checkstyle rule has also been added to prevent its usage in
main code from being reintroduced.

Previously @ServletComponentScan did not work when there was a
component index on the classpath as it made an assumption about
the concrete type of the BeanDefinitions produced by scanning that
does not hold true when an index is present.
This commit updates the scanning and the handlers to correct the
assumpution by working with a bean definition type that is produced
by scanning both when there is and when there is not an index present.
To prevent the problem from reoccuring, a test that uses and index
has been added and the import of ScannedGenericBeanDefinition is now
prohibited by Checkstyle.

This commit makes sure that we don't import a class from the Guava
library by mistake as it provides various utility classes with similar
names as our own.
