Indicate MediaCodec FLAC decoder doesn't support 32-bit below API 34

Browse Source 
This transforms the reported format support from `supported=YES` to
`supported=NO_EXCEEDS_CAPABILITIES`. Playback is still attempted in the
main demo app, and hangs as described in
https://github.com/androidx/media/issues/2197#issuecomment-2722322954.
