[Payments] canMakePayment() rate limit to iframe + top level origin.

Before this patch, if a payment service provider https://checkout.com
was being used in iframes for both https://momsshop.com and
https://popsshop.com, but with different sets of supported payment
methods, then canMakePayment() would be rejected with "NotAllowedError"
due to the rate limit on the iframe origin.

This patch changes the rate limiting to be based on the concatenation of
both iframe and top level origins instead of only iframe origin.

After this patch, if a payment service provider https://checkout.com is
being used in iframes for both https://momsshop.com and
https://bobsshop.com with different sets of supported payment methods,
then canMakePayment() will resolve with "true" or "false" according to
the user state instead of rejecting with "NotAllowedError".

This patch changes behavior for desktop and Android only, because iOS
implementation of PaymentRequest does not support iframes.

[Payments] Throttle canMakePayment() on security formatted URL.

url::Origin serialization should not be used for security checks,
according to url/origin.h. This patch switches desktop and iOS from
url::Origin to url_formatter::FormatUrlForSecurityDisplay(), which is
also used on Android. GURL::GetOrigin() should not be used because it
strips the path from file:// scheme URLs.

In addition, this patch replaces iOS hostname display with
url_formatter::FormatUrlForSecurityDisplay() as well to match the
Android behavior. Desktop PaymentRequest UI does not show the URL,
because the omnibox is visible during payment.
