Removed device-specific identifier and replaced with built-in AVFoundation check to see if codec is playable.
All devices that support iOS 15 (minimum required) support AC3/EAC3 so only check for FLAC (in native player) and HEVC (in both native and VLCKit).

Suppressed compile warning and did linting

Native player profile:
- Remove h263 from native direct play profile because it is unsupported in mpegts and ffmpeg does not support muxing it into mp4.
- Remove alac from native direct play profile because it is unsupported in mpegts, which is currently being used for HLS direct play streams.
- Remove flac check and flac from native profile because it is unsupported in mpegts.

VLCKit player profile:
- Add h263 to direct play profile because it was removed from base.
- Add in missing flv1 to direct play profile.
- Add alac to direct play profile because it was removed from base.
- Remove dca from direct play and transcoding profiles because I believe dts covers that codec.
- Remove flac, vp8, theora, msmpeg4v2, msmpeg4v3, wmv1, wmv2, vorbis, wmav2, pcm_s24le from transcoding profile because they are unsupported in mpegts.

WAV is an audio container format and should not have been in the video profile
