Reviewed by Chris Dumez and Dean Jackson.

The "XR immersive session" foreground activity is added when an
XR session starts so the web process has the foreground priority
to do rendering work. That activity gets invalidated when the
process is suspended. So if the process resumes again while an
XR session is still in progress, we need to add that foreground
activity again.
