[WebLayer] Move PaymentAppFactoryDelegate and PaymentAppFactoryParams

Changes:
* PRService takes over PaymentAppFactoryDelegate,
  PaymentAppFactoryParams from CPRService. These two interfaces need
  to be moved together, otherwise it would be subjected to the
  use-after-close issue of CL[1].
* Removed @Nullable from PRService#mPaymentOptions because it's not
  possible to be null[2].
* Wrapped canUserAddCreditCard in supportPaymentSheetBasedPaymentApp,
  because "whether users can add credit card" is not at the same
  semantic level as other methods of PaymentRequestService.
  PRService knows about basic-card payment app, and CPR knows about
  whether users can add credit card on the basic card payment app.
