This pulls in the types (based on the DefinitelyTyped repo) for `page.$eval` (and the `$eval` method on other classes). The `$eval` method is quite hard to type due to the way we wrap and unwrap ElementHandles that are passed to / returned from the `pageFunction` that users provide. Longer term we can improve the types by providing type overloads as DefinitelyTyped does but I've deferred that for now (see the `TODO` in the code for more details).
