[WebGPU] Tracer bullet part 6: Give a RunLoop to Instance

[Myles C. Maxfield]

The shared header has a function, wgpuInstanceProcessEvents(), which is supposed to synchronously call all outstanding callbacks. A natural way to do this is to hook this up to [NSRunLoop runMode:beforeDate:].

What's the layering between WebGPU and Foundation? How would a non-Apple port do this?

Non-Apple ports wouldn't use WebGPU.framework at all. They would use Dawn or wgpu. So the layering is just "Foundation is below WebGPU.framework."
