GH-3660: Invoke well-known lambdas explicitly

Browse Source 
Fixes https://github.com/spring-projects/spring-integration/pull/3660

* Change the `LambdaMessageProcessor` to invoke `Function`, `GenericHandler`,
`GenericSelector` & `GenericTransformer` explicitly without reflection.
This allows to avoid `--add-opens` for Java types to be used from reflections.
Plus this removes some overhead with native images.
And in general it is faster than reflection invocation.
