Original change's description:
> Set up eGPU/discrete support for MacOS.
>
> Pulled out of https://skia-review.googlesource.com/c/skia/+/271319.
>
> For Metal, will default to an eGPU or discrete GPU if one is available.
> For GL, will attempt to use a Radeon eGPU, and will fallback
> if one can't be found.
