#9178: AAC -profile options missing in help since 4.3

Summary of the bug:
How to reproduce:
With ffmpeg 4.2.3:
{{{
$ ffmpeg -hide_banner -help full | grep -C 10 aac_he_v2
-nssew <int> E..V..... nsse weight (from INT_MIN to
INT_MAX) (default 8)
-skip_top <int> .D.V..... number of macroblock rows at
the top which are skipped (from INT_MIN to INT_MAX) (default 0)
-skip_bottom <int> .D.V..... number of macroblock rows at
the bottom which are skipped (from INT_MIN to INT_MAX) (default 0)
-profile <int> E..VA.... (from INT_MIN to INT_MAX)

}}}
With ffmpeg 4.3 and higher:
{{{
$ ffmpeg -hide_banner -help full | grep -C 10 aac_he_v2
}}}
I think they went missing after commit
aee036cdd05499ae9dcba5b50e88f1cc02ea203e (avcodec: move aacenc profiles to
profiles.h) which i guess intended them to show up as options under the
aac and libfdk_aac codec but they are missing from that help also.
With ffmpeg 4.4.0:

Looking at the commit history for libavcodec/profiles.h it seems like the
same thing might have happened to other codec profile options:
