Reviewed by Sihui Liu.
When WebsiteDataStore::setThirdPartyCookieBlockingMode() is called (and it is
in these tests), it sends IPC to the web processes in its m_process map to
notify them of the new mode. But web processes that don't contain a local main
frame (such as web processes that exist only for cross-site iframes) are not
added to the WebsiteDataStore's map. So they aren't notified of the new mode.
So in those web processes,
WebProcess::singleton().thirdPartyCookieBlockingMode()
is wrong. (Checked by WebCookieJar::shouldBlockCookies() in these tests).
We fix this by ensuring that when a RemotePageProxy is added to a web process,
it's added to the WebsiteDataStore's map (currently web processes are only added
when a WebPageProxy is added).
