Currently if trace logging is enabled a StackOverflowException is thrown
when trying to resolve toString of the authentication.

Issue gh-11457
Previously AnonymousAuthenticationFilter accessed the SecurityContext to
determine if anonymous authentication needed setup eagerly. Now this is done
lazily to avoid unnecessary access to the SecurityContext which in turn avoids
unnecessary HTTP Session access.
Closes gh-11457
The Spring MVC changed the default behavior for trailing slash match
with https://github.com/spring-projects/spring-framework/issues/28552.
This causes failures in Spring Security's tests.
Setting the `useTrailingSlashMatch` to `true` ensures that Spring
Security will work for users who have modified the default configuration.
Specifing the request mapper with trailing slash path ensures that the tests
are successful when default behavior is used.
Closes gh-11451
