Re: [whatwg/fetch] Request needs to propagate concept of "main frame navigation" (#1327)

Well, "site for cookies" itself is not conveyed to the server.  It simply takes part in determining if `SameSite=Strict` cookies, etc, are sent to the server.

I do think, though, that if we had Sec-Fetch-Ancestors we could use that information for this as well.  (If its propagated through the fetch in a service worker.)  And of course since destination distinguishes between `document` and `iframe` it has the information as well, but it isn't propagated through the SW.
