Spring Security SecuredAuthorizationManager should allow customizing underlying authorization manager

Dependent on https://github.com/spring-projects/spring-security/issues/12232, exposing this authorization manager will allow applications to customize it. This can be handy in circumstances where, for example, authorization is externalized to service or database.

@jzheaux, @evgeniycheban, how can this functionality be used?

My goal is to add RoleHierarchy to @Secured functionality. Unfortunately, I couldn't find a way to customize SecuredAuthorizationManager by any customizer or BeanPostProcessor.
