Great work. Ruby is a meta programming super star.

Looks good, just one small typo.
Similar to the work in solidusio#6360, this improves the DSL for creating benefits. Rather than having to define one method that cares for applicability to a discountable, we now simply define that a benefit `#can_discount?` an object if its public interface has `#discount_{discountable_type}` defined. This does not change the implementation of the different methods, but that will come when we refactor the promotion system to use a single system of record for discounts. Then, different objects will need different discount records (line items and shipment use adjustments, but shipping rates use shipping rate discounts etc.). I'm not doing the work for adding deprecation warnings here, as this code was never meant to be overridden up to now. Also fixes some AI slop in the docs.
Instead, follow the deprecation message's instructions.
In the unlikely case people have used these modules, warn if they are included.

Summary
This applies the same refactoring that was done in #6360 to benefits, which have a similar API (they only discount when they can discount, the same way conditions only check eligibility if they are applicable).
This work is extracted from #6371. If we get this in earlier, that work gets easier to review.
Note that I have
notgone to the trouble to add deprecation warnings here.If anyone can show me real-world code that has actually created new benefits and that would benefit from a deprecation warning, I'll happily add them.Checklist
