Remove old phantom request path for launching prerender requests.

Remove old phantom request path for launching prerender requests.

After https://bugs.webkit.org/show_bug.cgi?id=85005 lands, but before https://bugs.webkit.org/show_bug.cgi?id=85021 lands, this patch removes a dependency on an old WebKit thunk.

This patch follows up on http://codereview.chromium.org/10198040/ , cleaning up
the old method for prerendering.  That patch left both methods in because WebKit
switched atomicly to the new interface in a separate CL that depended on it.

That WebKit CL was https://bugs.webkit.org/show_bug.cgi?id=85005 .  It has
landed, so this cleanup change won't break prerendering.

After this lands, I can then land https://bugs.webkit.org/show_bug.cgi?id=85021
.
