-----------
Add support for race-network-and-fetch-handler service worker router source
rdar://167982454
https://bugs.webkit.org/show_bug.cgi?id=305324
Reviewed by Chris Dumez.
We reuse the service worker preloader to implement
race-network-and-fetch-handler.
When receiving a response from the preloader, we use it and stop listening to
the fetch event handler.
Conversely, when receiving a response from the fetch event handler, we cancel
the preloader.
This allows to select the fastest route.
We update InstallEvent::addRoutes to check for fetch event registration in case
of race-network-and-fetch-handler route, and fix a potential use-after-move.
We update the IDL to accept race-network-and-fetch-handler and we update
InstallEvent::addRoutes according the spec.
Covered by existing WPT tests.
