[MP4] Make outputs CMAF compatible

- Added flag --mp4_include_pssh_in_stream, default to true. If it is
  set to false, the encrypted mp4 stream will not include pssh.
- Align BytesOfProtectedData to multiple of 16 bytes for cenc.
- Set TrackHeader flag to kTrackEnabled | kTrackInMovie |
                          kTrackInPreview
- Move mvex to after trak, required by HLS
- Add cmfc/cmfs compatible brands except for avc3/hev1, where CMAF
  requires single initialization switching set which is not supported.
- Set duration to 0 in tkhd, mdhd, mvhd.

Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
  a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
  tracks

Fixes b/36278260
