Based on #62896, only implements the BPM support part. * Implements BPM support in the AudioStreamOGG/MP3 importers. * Can select BPM/Bar Size and total beats in a song file, as well as edit looping points. * Looping is now BPM aware * Added a special importer UI for configuring this. * Added a special preview showing the audio waveform as well as the playback position in the resource picker. * Renamed `AudioStream::instance` to `instantiate` for correctness.
