Fix silent audio on tvOS with Atmos Continuous Audio Output (#928)

Browse Source 
With Atmos "Continuous Audio Output" enabled, some HDMI routes report
32 output channels, which mpv's audiounit AO cannot open - playback
stays silent while other (AVPlayer-based) apps work fine.

Update MPVKit to 0.41.0-n8.1.2, which builds mpv's avfoundation AO
(AVSampleBufferAudioRenderer, previously macOS-only) for iOS/tvOS
(mpvkit/MPVKit#73), and prefer it on tvOS via ao=avfoundation,audiounit
so mpv still falls back to audiounit if it fails to initialize. iOS and
macOS audio outputs are unchanged.

The MPVKit pin must be exactVersion: SwiftPM sorts the pre-release
identifier below 0.41.0, so a range starting at 0.41.0 never resolves
to it. Note this tag also bumps FFmpeg from 8.0 to n8.1.1.
