[HTML5] Run Audio process in thread when available This should fix some of the audio stuttering issues when the HTML5 export is compiled with threads support. The API should be ported to AudioWorklet to (hopefully) be perfect. That though, cannot be backported to 3.2 due to extra restriction of AudioWorklet (which only runs in SecureContext, and needs a polyfill for Safari).

Update copyright statements to 2021 Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆 (cherry picked from commit b5334d14f7a471f94bcbd64d5bae2ad853d0b7f1)

[HTML5] Refactor audio drivers. Implement AudioWorklet w/o threads. Performances are not great in general, bad on Firefox, on Chrome, well, it's an improvement compared to the way they broke ScriptProcessorNode. I'm actually surprised this works, it involves so many allocations, but there's no way around it when SharedArrayBuffer is not available :(.

[HTML5] Use browser mix rate by default on the Web. Browsers doesn't really like forcing the mix rate, e.g. Firefox does not allow input (microphone) if the mix rate is not the default one, Chrom* will exhibit worse performances, etc.

[HTML5] AudioWorkletAPI implementation. Rewrote AudioDriverJavaScript to support multiple processor nodes. The old (and deprecated) ScriptProcessorNode when threads are not available, and the new AudioWorklet API when threads are enabled. The new implementation uses two ring buffers and a shared state to communicated with the AudioWorklet thread. The audio.worklet.js JavaScript file is always added to the export template, but only really used (and download) in the thread build.
