Resolves https://github.com/spring-projects/spring-amqp/issues/1422
Broker-named queues did not work with `@RabbitListener` because the BPP
only passed the name of the queue bean, not the bean itself, into the
endpoint.
Support bean injection; fall back to the previous behavior if a mixture
of beans and names are encountered (the containers don't support both
types of configuration).
Add a note to the javadoc to indicate that broker-named queues are not
supported via `queuesToDeclare` and `bindings` properties; such queues
must be declared as discrete beans.

**cherry-pick to `2.4.x` & `2.3.x`**
