[3.x] [HTML5] Refactor audio drivers. Implement AudioWorklet w/o threads.

[Faless]

Same as #52649, for 3.x.

In this PR:

• Use browser mix rate by default on the Web. (done via [3.x] [HTML5] Use browser mix rate by default on the Web. #52723)
• Fix bug in AudioWorklet when reading output buffer (exception due to out-of-bound set). (cherry picked via Cherry-picks for the 3.x branch (future 3.4) - 17th batch #52841).
• Default HTML template prefers AudioWorklet on Chrome (this is questionable, and should probably be tested across devices). (will skip this for now).
• 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.

Works by sending chunks via postMessage, which is really slow.
I'm actually surprised this works, it involves so many allocations, but there's no way around it when SharedArrayBuffer is not available :(.

I've make a tiny test-project but i've stuttering/crackling audio :( Do I need to enable this AudioWorklet manually somewhere?

Yes, you need to enable threads in the HTML5 export preset and ensure the web server sends the required cross-origin isolation headers (on top of using HTTPS).

Thank you for the quick reply! Does this mean, that I'll never be able to test it by just pressing play? I always have to export first and then debug/play the game?

One-click deploy (the HTML5 logo at the top of the editor) will use threads if you have an HTML5 export preset marked as Runnable with threads enabled.
