I don't like this dependence on the AutofillManager. 

Let's do a couple of things so that we don't need it:

(1) full_card_request, card_unmask_delegate and payments_client 
 should really be in components/payments/core (optional)
   (1b) You will need to remove the dependence to AutofillClient* by instead
having AutofillClient implement risk_util.h (move to components) and pass that
to FullCardRequest. May need to have risk_util_impl.h/cc in
chrome/browser/autofill

(2) In this file, dialog_->ShowCvcUnmaskPrompt(credit_card, result_delegate)

(3) Ultimately the Cvc view controller should get all the things and be able to
create and hold on to the FullCardRequest!
  (3b) When it needs to pass the RiskUtil* to FullCardRequest, it can get it
from RiskUtilImpl (in chrome/browser/autofill).

+      factory->DriverForFrame(web_contents_->GetMainFrame());
+  autofill::payments::FullCardRequest* request =
+      driver->autofill_manager()->GetOrCreateFullCardRequest();
+
+  request->GetFullCard(
+      credit_card, autofill::AutofillClient::UNMASK_FOR_PAYMENT_REQUEST,
+      result_delegate, dialog_->GetFullCardRequestUIDelegate());
