document that requestAdapter can delay too #523

(Note of course this is a chance to the design document/rationale - not the spec.) |

| `GPU.requestAdapter` requests an adapter from the user agent. | ||
| It returns a Promise which resolves when an adapter is ready. | ||
| The Promise may not resolve for a long time - for example, the browser |

IDK that we need to describe why the adapter creation can be delayed: the explanation here is very graphics-centric. What if a backgrounded tab wants WebGPU just to perform computations? (I mean, it would be ok to disallow it to avoid cryptomining in the background but the explanation is still very graphics-centric.)

I don't think these descriptions are graphic-centric. They just assume you don't want background tabs consuming a lot of system resources (compute or memory). In any case this is just part of the design doc so I don't think that's necessarily a problem.

requestAdapter should delay until it can make the best choice about what adapter to return.
