Incognito mode behavior for 3rd party Android payment apps.

Changes to incognito mode behavior of web payments API in this patch:
1) PaymentRequest.canMakePayments() never returns false.
2) PaymentRequest.show() never returns NotSupportedError.
3) Chrome does not query IS_READY_TO_PAY in payment apps.
4) Chrome shows a warning message before invoking a payment app.

In addition, the "Request cancelled" rejection string is now an
AbortError, according to the spec change here:
https://github.com/w3c/browser-payment-api/commit/361e72084830d4c9aa3b09c8c1f08dc316dc71ce

The spec change is cosmetic and does not require web developers to
change their websites.
