Fixes https://github.com/spring-projects/spring-integration/issues/8654
Spring Framework has an ability to start dependant beans automatically
when we start the current one.
The `AbstractMethodAnnotationPostProcessor` is missing a bean dependency
registration causing errors in target applications when Messaging Annotations configuration is used.
* Add `registerDependentBean()` into an `AbstractMethodAnnotationPostProcessor` when we generate
and register a `ConsumerEndpointFactoryBean`
* Change one of the `ClientManagerBackToBackTests` configuration to rely on a `@ServiceActivator`
for `Mqttv5PahoMessageHandler` bean to ensure that change in the `AbstractMethodAnnotationPostProcessor`
has a proper effect
**Cherry-pick to `6.1.x` & `6.0.x`**
