avformat/flacdec, takdec: Use FFRawDemuxerContext directly

The beginning of the private contexts of both the FLAC and the TAK
demuxer currently mimick FFRawDemuxerContext: A pointer to an AVClass
followed by the AVOpt-enabled field raw_packet_size. Said field is only
used by the demuxers' read_packet functions via
ff_raw_read_partial_packet(), which treats the private context as an
FFRaawDemuxerContext. Yet this is fragile, so better include a
FFRawDemuxerContext struct at the beginning of said demuxers' private
contexts.
