[Payment Request] Error message screen

Displays an error message if:
1. PaymentResponse.complete() gets called with 'fail'.
2. The promise returned by PaymentRequestUpdateEvent.updateWith()
doesn't get settled in a reasonable amount of time.

Payment Request will cancel once the user dismisses the error screen.
