One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

[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).

Style: Harmonize header includes in platform ports This applies our existing style guide, and adds a new rule to that style guide for modular components such as platform ports and modules: Includes from the platform port or module should be included with relative paths (relative to the root folder of the modular component, e.g. `platform/linuxbsd/`), in their own section before Godot's "core" includes. The `api` and `export` subfolders also need to be handled as self-contained (and thus use relative paths for their "local" includes) as they are all compiled for each editor platform, without necessarily having the api/export matching platform folder in the include path. E.g. the Linux editor build will compile `platform/android/{api,export}/*.cpp` and those need to use relative includes for it to work.

[HTML5] Refactor audio drivers. Implement AudioWorklet w/o threads. Performances are not great in general, bad on Firefox, on Chrome, well, it could be an improvement. Leave it as a fallback for now, but can be forced via project settings if desired (or custom JavaScript logic via the "args" option). 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.

extern void godot_audio_resume();
Further refactoring to AudioDriver implementations after #69120. - Rename all instances of `capture_start()` and `capture_end()` to their new names. Fixes #72892. - More internal renames to match what was started in #69120. - Use `override` consistently so that such refactoring bugs can be caught. - Harmonize the order of definition of the overridden virtual methods in each audio driver. - Harmonize prototype for `set_output_device` and `set_input_device`.

[HTML5] AudioWorklet API 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 downloaded) in the thread build.
