handling `label`

[greggman]

Here's some code that effectively wraps label

const gpuBufferPrototypeDescriptors = Object.getOwnPropertyDescriptors(GPUBuffer.prototype);

Object.defineProperty(GPUBuffer.prototype, 'label', {
  get() {
    const label = gpuBufferPrototypeDescriptors.label.get.call(this);
    console.log('label is:', label);
    return label;
  },
  set(label) {
    gpuBufferPrototypeDescriptors.label.set.call(this, label);
    console.log('label set to:', label);
  }
});

I'm not sure how what should be handled in capture. It's seems like it would be nice if label setting was just another command since I've done stuff like this in native code in the past

buffer.label = `data for frame ${frameNumber}`
