[iOS] [GPU] Silence warning about com.apple.audio.AudioComponentRegistrar in the WebContent process
https://bugs.webkit.org/show_bug.cgi?id=225547
<rdar://problem/77334436>
Reviewed by Per Arne Vollan.
We block access to various media things (like 'com.apple.audio.AudioComponentRegistrar') when the GPU Process is being used.
Some AudioToolbox code continues to try to connect even though we are not activating relevant parts of the audio subsystem.
AudioToolbox doesn't care about this blocked connection when running in this mode, but they have not had a chance to modify
the framework to avoid attempting to connect.
To avoid spurious logging and telemetry, silence the sandbox violation when the GPU Process is active.
