Original change's description:
> Add 'is ready to pay' restriction for Web Payment Handlers on Android
>
> This CL adds logic to check the state of the canMakePayment pref before
> issuing the 'is ready to pay' query to service worker payment handlers
> on Android.
>
> This CL also updates the `PaymentAppFactoryDelegate` interface by
> removing the default implementation of `prefsCanMakePayment()`, forcing
> all implementers to provide one.
