GH-3957: Add JmsInboundGateway.replyToExpression (#8560)

* GH-3957: Add JmsInboundGateway.replyToExpression

Fixes https://github.com/spring-projects/spring-integration/issues/3957

Sometimes we cannot use a standard `JmsReplyTo` property for sending replies from the server.
A `DestinationResolver` API does not have access to the request message.

* Introduce a `ChannelPublishingJmsMessageListener.replyToExpression` property to evaluate
a reply destination against request JMS `Message`
* Use this expression only of no `JmsReplyTo` property
* Expose this property on Java DSL level
* To simplify end-user experience with lambda configuration for this property, introduce a `CheckedFunction`
which essentially re-throws exception "sneaky" way

* Fix Javadoc for `CheckedFunction`

* * Fix language in docs
* Fix Javadocs lines length
* Regular `catch` and re-throw in the `CheckedFunction`
