Kongqun Yang d007ddf20b [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

Kongqun Yang bee59bc2fc Enable generate_dash_if_iop_compliant_mpd by default 
This will move ContentProtection element from Representation
to AdaptationSet.

Shaka Player already supports AdaptationSet switching
urn:mpeg:dash:adaptation-set-switching:2016;

ExoPlayer does not support it yet. Filed
https://github.com/google/ExoPlayer/issues/2431 to track the issue.

(ExoPlayer does not like having ContentProtection in Representation
anyway)

Closes b/34691105

Kongqun Yang d08f6ae0cc Fix cbcs/cens behavior when applied to non video tracks 
- Tracks other than video are protected using whole-block full-sample
  encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
  equivalent to a pattern of 1:0. This is different to the non pattern
  encryption counterparts.
- Also updated the code to allow the existence of other protection
  schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
  constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.
