Embree on Apple Silicon

Related issue: stechyo/godot-steam-audio#53

System Information
Please provide the following information about your system:

• Steam Audio version: 4.5.3
• Operating System and version: macOS
• (Optional) CPU architecture (e.g. x86-64, armv7): ARM

Issue Description
It seems that Embree doesn't work on Apple Silicon (macOS + ARM). From what I see here it seems that the internal embree devices are only enabled on x86, but I'll confess I don't know much about steamaudio internal code. Is there any plan to support embree on this platform?

@stechyo Steam Audio currently uses Embree v2.17.2, which is an older version, and does not support ARM CPUs. The latest versions of Embree, v4.3.x, do support ARM CPUs, so we would have to update Steam Audio to use the newer version. This newer version of Embree has breaking changes to the API, so it would require a non-trivial, but hopefully a reasonable amount of work to update Steam Audio to use the new API.
