If a page has an opener, with site isolation we will need to get that information
from the UI process if the opener is in a different process than the opened page.

This is the first step to better supporting window.open and iframe combinations
with site isolation.  The next step is having the BrowsingContextGroup not only
keep track of what processes are in the group for what domain, but also keep track
of what pages are in the group so they can all have RemoteFrames injected into a
new process in the group.
