[WFCORE-38] Add console option to target of console-handler

Adds an option to use the ```System.console()``` for the console-handler. Kept default of ```System.out```.
Something like:
.addRejectCheck(SIMPLE_EXPRESSIONS, TARGET)
.addRejectCheck(new SimpleRejectAttributeChecker(new ModelNode("console"), TARGET)
.end();

As per the BaseAttributeTransformationDescriptionBuilder.addRejectCheck() javadoc, the reject checkers should be evaluated in the order they are added.
