Artem Bilan e98169146b GH-3288: Add Kotlin DSL transform(Transformer) ...

Fixes https://github.com/spring-projects/spring-integration/issues/3288

* For better end-user experience with Kotlin DSL and get a gain from
existing `Transformer` implementations add a `transform(Transformer)`
EI-method into the `KotlinIntegrationFlowDefinition`
* Also add `filter(MessageSelector)` for any out-of-the-box `MessageSelector`

**Cherry-pick to 5.3.x**
