Fixes: https://github.com/spring-projects/spring-integration/issues/9683
Since we don't support SpEL-based Control Bus functionality anymore,
there is no need to keep separate `controlBusOnRegistry()`
* In all DSLs Deprecate `controlBusOnRegistry()` and restore `controlBus()` which is now fully based
on the `ControlBusCommandRegistry`
* Deprecate now out of use `<control-bus use-registry="">` attribute
* Fix `ControlBusParser` to not deal with `use-registry` attribute anymore
* Remove deprecated before `ExpressionControlBusFactoryBean` and `ExpressionCommandMessageProcessor`
* Remove `use-registry` from test configs
* Fix `ControlBusChainTests` to rely on a new Control Bus functionality
