Description Brent Fulgham 2020-12-10 14:53:16 PST 
This IOKit class appears to only be used by media, and only on Apple Silicon. Dynamically extend access to this class for Apple Silicon builds if the GPU process is not being used.

This patch includes additional telemetry to confirm that it is not needed on Intel, and not for any other purposes.
