feat(electron): adapts to default audio input/output device changes (#11815)

Enable automatic adoption of new default audio devices upon detection.

1. add `AggregateDeviceManager` to watch for audio device changes, creating & maintaining `AggregateDevice` instances and cleaning up
2. use a workaround of `FastFixedIn` to deal with resampling delay issue (this is low quality and have some artifacts in the resampled audio)
