COOP should be disregarded in insecure contexts. This was not done
properly and only avoided storing the COOP value in the RenderFrameHost
after using it to potentially do a BrowsingInstance swap. This patch
fixes the issue by completely stripping the response of its COOP value
in such cases.

Also fixes CrossOriginOpenerPolicyBrowserTest to use an HTTPS server
and add a test that verifies it does not work over HTTP.
