fix(player): show AAC instead of mp4a.40.2 in ExoPlayer track labels

Browse Source 
ExoPlayer reports RFC 6381 codec IDs (mp4a.40.2, ec-3, dtsc) where mpv
reports ffmpeg names, so the audio track picker and performance overlay
showed raw identifiers instead of friendly names on the ExoPlayer path.

Normalize RFC 6381 audio IDs in CodecUtils.formatAudioCodec, route the
performance overlay's audio codec through it, and cover the video IDs
(hvc1/hev1, av01, vp09) that fell through the overlay's matcher.
