What's the deal with all the extra "DOM"s added to the generated code? Name conflict? Can you add an explanation to the changelog?

> Source/WebCore/Modules/webaudio/AudioWorkletGlobalScope.h:53
> +    float sampleRate() const { return 44100; }

This number should probably be in its own constexpr with a clear name to explain it (unless you expect this to go away real soon).

> Source/WebCore/Modules/webaudio/AudioWorkletProcessorConstructor.idl:31
> +]callback AudioWorkletProcessorConstructor = AudioWorkletProcessor (object options);

Please add a space after the closing ].

If they were going to stay like this for a long time we could use static constexpr.

This is going to go away real soon to return the actual context sample rate. I could have returned 0 here but I figured I would return a realistic sample rate.

Yes, there was a name conflict since we now have both JSAudioWorkletProcessor and JSAudioWorkletProcessorConstructor classes (Due to having AudioWorkletProcessor.idl and AudioWorkletProcessorConstructor.idl). The issue was that the DOMConstructor for JSAudioWorkletProcessor was named JSAudioWorkletProcessorConstructor too. So I renamed it to JSAudioWorkletProcessorDOMConstructor.
