I think there needs to be a check if curve has length < 2, according to curve's spec: https://www.w3.org/TR/webaudio/#dom-waveshapernode-curve. Maybe it can inside of setCurve, or we can also catch it earlier.

Why &&, it does not seem we move curve inside?

Win failure seems legit, please fix it before landing.

This is a setter so && makes sense. The generated bindings are also passing us an rvalue reference. It is true that this implementation is currently not leveraging this (it probably could with some further refactoring) but it could at some point.

I was missing a #if ENABLE(WEB_AUDIO)
