This patch introduces a new type of content process, which has a dynamic name.
This type of content process is labeled as `webIsolated=${SITE_ORIGIN}` and is
used within fission-enabled windows.
To enable this, additional information about the fission status of the target
window must be passed into E10SUtils. This was done by updating every call site
manually to pass an extra boolean. A better solution perhaps should be used in
the future.
With this patch enabled, we now perform process switches, but only when
navigating to HTTP URIs. If we navigate to a non-HTTP URI in an iframe with
fission enabled, it will not behave correctly. This must be done in a
follow-up.
