Stripe equivalent for openNativePaySetup from tipsi-stripe

[bill-pairaktaridis]

tipsi-stripe, from which we are migrating, had a method called openNativePaySetup which allowed us to open Apple Wallet from within our app, in case the user hadn't set it up (seen here: https://github.com/tipsi/tipsi-stripe/blob/2e777c704bd00833fa1642035b03886049563846/src/Stripe.js#L232).

Describe the solution you'd like
We would like to have a method or way to do the same, as well as to be able to check if Apple Pay is support but not set up. Right now, if I'm not mistaken, isApplePaySupported checks for both, so there's no in-between.
