`Object.prototype.__proto__`, HTML `String` methods, etc.

Implement NumberToString properly

See https://tc39.github.io/ecma262/#sec-tostring-applied-to-the-number-type. Right now we are just delegating to the host: https://github.com/devsnek/engine262/blob/678fec88552a77b8feebbc6f0fe45e7336b454c1/src/abstract-ops/type-conversion.mjs#L288-L305

New elements: ``, ``, ``, ``, ``, ``, ``. New method: `SVGSVGElement.createSVGRect` Auxiliary classes: - DOMRect (new) - DOMRectReadOnly (new) - SVGAnimatedPreserveAspectRatio (new, reflection support) - SVGAnimatedRect (new, reflection support)...

Hi, I'm the maintainer of the [libilbc](https://github.com/TimothyGu/libilbc) library, which essentially extracts out the parts of WebRTC needed to support a standalone iLBC codec. It's used by [FFmpeg](https://ffmpeg.org/) and is packaged...

Large objects deadlock autocompletion
