avcodec/codec_internal: add cap for ICC profile support
Codecs that can read/write ICC profiles deserve a special capability so
the common logic in encode.c/decode.c can decide whether or not there
needs to be any special handling for ICC profiles. The motivation here
is to be able to use it to decide whether or not an ICC profile needs to
be generated in the encode path, but it might as well get added to
decoders as well for purely informative reasons.
It's not entirely clear to me whether the "thp" and "smvjpeg" variants
of "mjpeg" should have this capability set or not, given that the code
technically supports it but I somehow doubt these files may contain
them. In either case, this cap is purely informative for decoders so it
doesn't matter too much either way.
It's also not entirely clear whether the "amv" encoder should signal ICC
profile support, but again erring on the side of caution, we probably
*shouldn't* be generating (and encoding!) ICC profiles for this type of
media file.
