  Support Apple Pay in cross-origin iframes with allow=payment attribute

Reviewed by Dean Jackson.

This bug happens because there is a check for the parentDocument to have
the same security origin than the child document, contrary to what the
[Payment Request API spec from W3 states](https://www.w3.org/TR/payment-request/#using-with-cross-origin-iframes).
The solution is to remove the check for the same parentDocument origin.

* LayoutTests/http/tests/paymentrequest/payment-allow-attribute.https-expected.txt:
- Update tests according to new behavior
* Source/WebCore/Modules/applepay/PaymentSession.cpp:
(PaymentSession::canCreateSession):
- Remove check for same parent origin since we have allow payment check before
