INT-4064: Simplify IdempotentReInt Java Config

JIRA: https://jira.spring.io/browse/INT-4064

We configure `IdempotentReceiver` via `<int:idempotent-receiver>` component or `@IdempotentReceiver` annotation.
In case of regular Java config, e.g. direct `ConsumerEndpointFactoryBean` usage or Java DSL,
it isn't possible to configure `idempotentReceiverInterceptor` enough easy

* Introduce `if...else` logic into `ConsumerEndpointFactoryBean` to proxy `MessageHandler`,
if `adviceChain` contains an newly-introduced `HandleMessageAdvice`.
And do that independently if `MessageHandler` is `AbstractReplyProducingMessageHandler`
* Make `idempotentReceiverInterceptor extends HandleMessageAdvice`
* Skip `HandleMessageAdvice` in the `AbstractReplyProducingMessageHandler`
* Add advice applying logic into the `AbstractMethodAnnotationPostProcessor` as well

Introduce `HandleMessageAdvice` marker interceptor to cover the case when an `Advice` can be advices as well.
Remove unused `setAdviceChainIfPresent()` method in the `AbstractMethodAnnotationPostProcessor`

Document `HandleMessageAdvice`

Increase wait latch timeouts in the `LockRegistryLeaderInitiatorTests`
