[whatwg/fetch] Attempt to reuse preloaded responses. (PR #1342)

Before any particular fetch steps are performed, see if there is a
matching request already in the preload store and consume it.

This is called from the main fetch to avoid race conditions.

Depends on https://github.com/whatwg/html/pull/7260
