[LayoutTests] No longer skip importing payment-request tests from WPT

Tests will be imported at the next auto-import

From running locally, there are 6 that fail (to be investigated). I will submit TestExpectations once the tests are imported

Verify behavior of PaymentRequest constructor.

This patch adds web platform tests that verify behavior of
PaymentRequest constructor. To match the spec, PaymentRequest
constructor in this patch has been changed to:
- Check for secure context before validating any parameters.
- Check the amount value first before checking the rest of the fields in
  each line item.
- Determine the selected shipping option even if requestShipping is
  false.
- Validate shipping options even if requestShipping is false.
- Validate shipping options before checking for duplicate shipping
  option IDs.
- Allow empty line item labels (but discourage via a console warning).
- Allow empty shipping option ID (but discourage via a console warning).
- Allow empty list of modifiers.

Because of changes in the WebIDL, certain conditions are not possible,
so they are ensured via DCHECK() in this patch instead of if statements
before this patch:
- Total is always present.
- Every line item has a label and amount.
- Every amount has value and currency.
- Every shipping option has an ID.
- Shipping type is always valid.

Invalid shipping type ("delivery", "shipping", or "pickup") is now
impossible because the WebIDL specifies it as an enum. Therefore,
there's no need for additional validation there.

To help developers better decipher the behavior of the API, error
messages have been improved in this patch. For example:
  "'-1/3' is not a valid amount for total."

commit 7d433cc2ac0b3e36e6753e84fbfc9253aac646d8

Verify behavior of PaymentRequest.show() method, part 1.

Before this patch, Chrome on Android would allow only one instance of
PaymentRequest per browser process to be displayed, but desktop had no
such restriction.

This patch adds a check for currently displaying PaymentRequest UI on
desktop. The currently displayed instance of PaymentRequest is kept
track of in PaymentRequestWebContentsManager.

After this patch, Chrome on desktop allows only one instance of
PaymentRequest per tab to be displayed.

From https://w3c.github.io/browser-payment-api/#show-method
"If the user agent's "payment request is showing" boolean is true, then
 return a promise rejected with an "AbortError" DOMException."

From https://w3c.github.io/browser-payment-api/#dfn-payment-request-is-showing
"The user agent as a whole has a single "payment request is showing"
 boolean, initially false. This is used to prevent multiple
 PaymentRequests from being shown, via their show() method, at the same
 time."
