Forward notifications from the UI process to the WebContent process
https://bugs.webkit.org/show_bug.cgi?id=275874
rdar://129602281
Reviewed by Sihui Liu and Ben Nham.
When a notification is being observed in the WebContent process, an OS fault is
generated, unless this
notification has been added to an allow list in the entitlements. The purpose
of this telemetry is to
detect which notifications we need to forward from the UI process. This patch
adds a set of notifications
that has generated faults to the allow list. The notifications are also added
to the list of forwarded
notifications, and to the sandbox so that they can be reposted in the
WebContent process.
It is important to remove these OS faults by adding the notifications to these
allow lists, since they
can be costly in terms of CPU usage.
