Update Safe Browsing cookie logging

Set-Cookie headers are filtered out of network::mojom::URLResponseHead
to support sending response info to renderer processes. In order to
observe cookie writes, we need a trusted_params.cookie_observer. This CL
updates the authenticated request cookie reset logging to use that
instead.
