Add UsePredicateNot to replace cast-and-negate with Predicate.not(..) (#1072)

* Add `UsePredicateNot` to replace cast-and-negate with `Predicate.not(..)`

Targets Java 11+ code like `((Predicate<T>) lambdaOrMethodRef).negate()` and
rewrites to `Predicate.not(lambdaOrMethodRef)`.

* Regenerate `recipes.csv`

* Use `Expression.unwrap()` in `UsePredicateNot`
