  Using Cross-Origin-Opener-Policy HTTP header disables the back/forward cache

Reviewed by Per Arne Vollan.

When process-swapping on navigation response, due to the Cross-Origin-Opener-Policy HTTP header,
we would fail to create a SuspendedPageProxy for the page in the previous WebProcess, which
would essentially disable the back/forward cache.

This is not efficient and also causes issues when navigating back to a history item that was
created by JavaScript via history.pushState().
