Attachment: Bug 1765777 - Resolve FetchEvent.preloadResponse when the response is available not the response end. r=#dom-worker-reviewers.

In the previouse implementation, FetchEvent.preloadResponse is resolved when the response fetching finishes.
However, ServiceWorker respond letency could be increased since waiting for preloadResponse finishes.
The patch try to resolve FetchEvent.preloadResponse earlier when the response is available.
