[Payment Request] Implement PaymentRequest.canMakePayment()
https://bugs.webkit.org/show_bug.cgi?id=178048

Reviewed by Youenn Fablet.

LayoutTests/imported/w3c:

* web-platform-tests/payment-request/payment-request-canmakepayment-method.https-expected.txt: Removed.

Source/WebCore:

Test: http/tests/paymentrequest/payment-request-canmakepayment-method.https.html

* Modules/applepay/paymentrequest/ApplePayPaymentHandler.cpp:
(WebCore::ApplePayPaymentHandler::convertData): Moved
ApplePayRequest-to-ApplePaySessionPaymentRequest conversion from here to show().
(WebCore::ApplePayPaymentHandler::show): Returned an exception if
ApplePaySessionPaymentRequest conversion fails.
(WebCore::shouldDiscloseApplePayCapability): Checked if we are in an ephimeral session or if
Settings::applePayCapabilityDisclosureAllowed() is false.
(WebCore::ApplePayPaymentHandler::canMakePayment): Called
PaymentCoordinator::canMakePayments() or PaymentCoordinator::canMakePaymentsWithActiveCard()
depending on shouldDiscloseApplePayCapability().
* Modules/applepay/paymentrequest/ApplePayPaymentHandler.h:
* Modules/applepay/paymentrequest/ApplePayRequest.h:
* Modules/applepay/paymentrequest/ApplePayRequest.idl: Defined merchantIdentifier.
* Modules/paymentrequest/PaymentHandler.h:
* Modules/paymentrequest/PaymentRequest.cpp:
(WebCore::parse): Moved JSON-parsing to here from show().
(WebCore::PaymentRequest::show): Returned the exception from PaymentHandler::show().
(WebCore::PaymentRequest::canMakePayment): For each payment method, try to create a
PaymentHandler.
For the first valid PaymentHandler, call canMakePayment() and pass a lambda that resolves
the promise.
* Modules/paymentrequest/PaymentRequest.h:
* Modules/paymentrequest/PaymentRequest.idl: Added CallWith=Document annotations to show()
and canMakePayment().
