Description

Enables AOM runtime CPU detection on macOS.

Motivation and Context

Runtime CPU detection in AOM has been extended to properly detect ARM64 CPUs and enable NEON features if possible - disabling the runtime detection has been found to lead to crashes when attempting to record using AOM on Apple Silicon Macs.

Fixes obsproject/obs-studio#10226.

How Has This Been Tested?

Tested on macOS 14.3.1 doing AOM recordings with an updated libavcodec.dylib inserted into OBS app bundle.
