Restrict background fetch loads to HTTP family
https://bugs.webkit.org/show_bug.cgi?id=253073
rdar://problem/106026139

Reviewed by Alex Christensen.

Update BackgroundFetch to handle the case of a synchronously failure.
Previously, the responseReady promise would not resolve given the failure will happen before the responseReady callback is registered.
We are now making sure to answer the responseReady callback if the failure happened before the registration.

Add HTTP check in BackgroundFetchLoad to fail lood immediately for non HTTP loads.

We update the WPT test to cover the case where the fetch registration happens but the load fails.
This is inline with other checks like CSP done at individual fetch level.
