Roll FFmpeg DEPS for M56

Includes FFmpeg support for Opus audio decode, though disabled in
  FFmpegAudioDecoder until OpusAudioDecoder is removed later.

Updates Chromium parsing and expectations of updated FFmpegUTCDate
  format (it changed from YYYY-MM-DD HH:MM:SS to
  YYYY-MM-DDTHH:MM:SS.xxxxxxZ) used by FFmpegDemuxer's
  ExtractTimelineOffset() helper and related tests. Now uses
  much more lenient base::Time::FromUTCString() for this conversion.

Includes changes to not use deprecated AVStream.codec:
  ScopedPtrAVFreeContext is used instead of ~FFmpegGlue() iterating over
    closing of deprecated AVStream.codec in each stream.
  FFmpegDemuxer, FFmpegDemuxerStream, and various ffmpeg_common updates
    to work using conversion from AVStream.codecpar. Note that
    AVCodecParameters does not include coded_width or coded_height
    information, and AVStream.parser's coded size fields are not
    populated by av_find_stream_info(). We just use the width and
    height as hints of coded size in AVStreamToVideoDecoderConfig().
    AVStreamToVideoDecoderConfig() is also updated to allow 1 less
    invalid extradata case (see bug 517163).
  FFmpeg*BitStreamConverter, callers and related tests changed to use
    AVCodecParameters instead of AVCodecContext.
  AudioFileReader, MediaFileChecker, AudioVideoMetadataExtractor updated
    to work using conversion from AVStream.codecpar. Note that
    AVCodecContext built from an AVCodecParameters does not have its
    time_base populated until after avcodec_open2(), so
    AudioFileReader::SeekForTesting() uses AVStream.time_base instead.
  FakeMediaSource changed to use AVStreamToAVCodecContext helper intead
  of deprecated AVStream.codec, and to use AVFrame.pts instead of
  deprecated AVFrame.pkt_pts.

Updates regressed FFmpeg regression tests:
  Cr222754, CR234630b no longer get PIPELINE_OK when starting the
  pipeline. Test expectations updated.
