<h3>Log Message</h3>
<pre>[Cocoa] Silence uninteresting sandbox reports
https://bugs.webkit.org/show_bug.cgi?id=225713
<rdar://problem/77483132>

Reviewed by Per Arne Vollan.

Telemetry from the recently released iOS and macOS updates show a set of uninteresting sandbox violations. Most of
these are harmless, but all of them involve some runtime cost and may prevent code from making the best use of
available hardware and should be permitted.

These changes also bring the various sandboxes into better alignment, as many of these items had previously been
added to one of the other sandboxes.
