Currently, Chromium disregards Accept-CH-Lifetime header on iframe
navigation responses. This CL changes Chromium behavior to
accept ACL header on iframe navigation responses provided the origin
of the response matches the origin of the main frame navigation.

This behavior is compliant with the updated client hints spec.

WPT tests will come in a subsequent CL.
