ipcm is defined by ISO/IEC 23003-5, not defined by quicktime. After
adding ISO/IEC 23003-5 support, we don't need it for ticket #9219.

The fLaC and dfLa box IDs have been registered with the MP4 RA
(they are now listed at https://mp4ra.org/#/codecs) and support
for muxing FLAC in MP4 has been experimental in ffmpeg for
6 years now, since Nov 21, 2016
This patch removes the experimental status and removes the MP4
object type, as none has been registered for FLAC as it was not
deemed necessary.

Some files I have from circa year 2000 are 16:9 NTSC DV video
encoded as QuickTime with Radius SoftDV. This marked 4:3 videos
with the box 'dvc ' for NTSC or 'dvcp' for PAL, which are already
supported, but 16:9 videos as 'dvl ' or 'dvlp', which were not.
Adding these to the list for DV codec processing gives the
expected metadata and playback.
I have not tested PAL as I have no sample data, only NTSC.

In 1c42fd9323 the ipcm identifier was
added in order to demux additional raw audio from Sony MP4 files.
Unfortunately, it was not noticed that this same list is utilized
for muxing as well, thus causing ipcm to get preferred compared
to the identifier officially specified in QTFF documentation.
This fixes the order of preference for 24bit PCM, where ipcm is
still allowed, but in24 is the first match - thus being preferred.
Fixes fate-acodec-pcm-s24be.
AVID streams - currently handled by the AVRN decoder - can be (depending
on extradata contents) either MJPEG or raw video. To decode the MJPEG
variant, the AVRN decoder currently instantiates a MJPEG decoder
internally and forwards decoded frames to the caller (possibly after
cropping them).
This is suboptimal, because the AVRN decoder does not forward all the
features of the internal MJPEG decoder, such as direct rendering.
Handling such forwarding in a full and generic manner would be quite
hard, so it is simpler to just handle those streams in the MJPEG decoder
directly.
The AVRN decoder, which now handles only the raw streams, can now be
marked as supporting direct rendering.
This also removes the last remaining internal use of the obsolete
decoding API.
The NUT and avi demuxers only need ff_codec_movvideo_tags and so this
removes a dependency on the rest of isom.c as well as on mpeg4audio.c
(which isom depends on); it is similar for the Matroska demuxer and
muxers, except that the mpeg4audio.c dependency can't be avoided.
