[3D] macOS support

[kvark]

I'm able to run vange-rs on macOS via Angle:

The only thing that's needed is copying Angle binaries somewhere, similar to how we do it on Windows. I grabbed these from VisualStudioCode, attaching here: Angle-macOS-arm64.zip

Obviously there is something wrong with the colors or gamma, haven't figured this out yet.

Interesting warning here, maybe coming from Angle?

UNSUPPORTED (log once): gldCopyBufferSubData: NEEDS IMPLEMENTATION

The colors are fixed by https://github.com/kvark/vange-rs/commit/7130e23504d38341635f9606c48798f95541e0e8
