Fenced frames: Disable Open Link in Profile context menu options when
network is revoked.

Fenced frames(FF) can disable network access by invoking FF API:
window.fence.disableUntrustedNetwork().

After the network access is revoked, FF will get access to cross-site
data, for example, via shared storage get API.

The principle is no network request can be made using URLs in a
network-disabled FF, including user triggered main-frame navigations.
This is because the URL can leak cross-site data, for example, by
appending the cross-site data to the URL.

This CL disables Open Link in Profile context menu options when FF
network is revoked.
