README/index.html: Update Web resources & URLs, add details about audio-backens per platform and contained openal-soft library

Promoted ALAudioSink to JOAL from JOGL, while pushing the general interfaces to (err) GlueGen,
yeah .. but didn't wanted to create another module.

ALAudioSink got some fixes for performance/low-latency
as tested and evaluated with a simple synthesizer
https://jogamp.org/cgit/joal.git/tree/src/test/com/jogamp/openal/test/manual/Synth02AL.java

This might be useful for other projects and I may push it in JOAL's util package
to easily produce sounds and change frequency + amplitude on the fly.
However, there are better full feature synthesizers like JSyn,
and we might want to discuss adding JOAL to its backends?

I also validated details of ALAudioSink and realized AL_SOFT_buffer_samples
is gone since openal-soft 1.18.0.
Hence I patched it accordingly and tested w/ GLMediaPlayer and 4-6 channel audio, working again.

OpenAL-Soft v1.23.1 and our builds have the following backends:

* Windows:
  -- OpenAL Soft: Audio-Backends: WinMM, DirectSound, WASAPI, WaveFile, Null

* GNU/Linux:
  -- OpenAL Soft: OpenAL: PipeWire, PulseAudio, ALSA, OSS, SndIO (linked), WaveFile, Null

* Android/Linux:
  -- OpenAL Soft: Audio-Backends: PipeWire, OpenSL, WaveFile, Null

* OSX
  -- OpenAL Soft: Audio-Backends: CoreAudio, WaveFile, Null


Will be released w/ JogAmp v2.5.0 and is contained in the RC builds.
