Add Rodio audio pipeline as alternative to current LiveKit pipeline (#36607)

Rodio parts are well tested and need less configuration then the livekit
parts. I suspect there is a bug in the livekit configuration regarding
resampling. Rather then investigate that it seemed faster & easier to
swap in Rodio.

This opens the door to using other Rodio parts like:
 - Decibel based volume control
 - Limiter (prevents sound from becoming too loud)
 - Automatic gain control

To use this add to settings:
```
  "audio": {
    "experimental.rodio_audio": true
  }
```

Release Notes:

- N/A
