And rename it to ff_encode_add_stats_side_data() and move its
declaration to encode.h. Also constify the error pointee.

The aim of this is twofold: a) Clang warns when setting a deprecated
field in a definition and because several of the widely set
AVCodec fields are deprecated, one gets several hundred warnings
from Clang for an ordinary build. Yet fortunately Clang (unlike GCC)
allows to disable deprecation warnings inside a definition, so
that one can create simple macros to set these fields that also suppress
deprecation warnings for Clang. This has already been done in
fdff1b9cbf for AVCodec.channel_layouts.
b) Using macros will allow to easily migrate these fields to internal ones.

I went through all codecs and put them into five basic categories:
1. JPEG range only
2. MPEG range only
3. Explicitly tagged
4. Broken (codec supports both but encoder ignores tags)
5. N/A (headerless or pseudo-formats)
Filters in category 5 remain untouched. The rest gain an explicit
assignment of their supported color ranges, with codecs in category
4 being set to MPEG-only for safety.
It might be considered redundant to distinguish between 0 (category 5)
and MPEG+JPEG (category 3), but in doing so we effectively communicate
that we can guarantee that these tags will be encoded, which is distinct
from the situation where there are some codecs that simply don't have
tagging or implied semantics (e.g. rawvideo).
A full list of codecs follows:
JPEG range only:
- amv
- roqvideo
MPEG range only:
- asv1, asv2
- avui
- cfhd
- cljr
- dnxhd
- dvvideo
- ffv1
- flv
- h261, h263, h263p
- {h263,vp8}_v4l2m2m
- huffyuv, ffvhuff
- jpeg2000
- libopenjpeg
- libtheora
- libwebp, libwebp_anim
- libx262
- libxavs, libxavs2
- libxvid
- mpeg1video, mpeg2video
- mpeg2_qsv
- mpeg2_vaapi
- mpeg4, msmpeg4, msmpeg4v2, wmv1, wmv2
- mpeg4_omx
- prores, prores_aw, prores_ks
- rv10, rv20
- snow
- speedhq
- svq1
- tiff
- utvideo
Explicitly tagged (MPEG/JPEG):
- {av1,h264,hevc}_nvenc
- {av1,h264,hevc}_vaapi
- {av1,h264,hevc,vp8,vp9,mpeg4}_mediacodec
- {av1,h264,hevc,vp9}_qsv
- h264_amf
- {h264,hevc,prores}_videotoolbox
- libaom-av1
- libkvazaar
- libopenh264
- librav1e
- libsvtav1
- libvpx, libvpx-vp9
- libx264
- libx265
- ljpeg
- mjpeg
- vc2
Broken (encoder ignores tags):
- {av1,hevc}_amf
- {h264,hevc,mpeg4}_v4l2m2m
- h264_omx
- libxeve
- magicyuv
- {vp8,vp9,mjpeg}_vaapi
N/A:
- ayuv, yuv4, y41p, v308, v210, v410, v408 (headerless)
- pgmyuv (headerless)
- rawvideo, bitpacked (headerless)
- vnull, wrapped_avframe (pseudocodecs)
There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Makes it robust against adding fields before it, which will be useful in
following commits.
Majority of the patch generated by the following Coccinelle script:
@@
typedef AVOption;
identifier arr_name;
initializer list il;
initializer list[8] il1;
expression tail;
@@
AVOption arr_name[] = { il, { il1,
- tail
+ .unit = tail
}, ... };
with some manual changes, as the script:
* has trouble with options defined inside macros
* sometimes does not handle options under an #else branch
* sometimes swallows whitespace
Unnecessary since acf63d5350;
also avoids relocations.
