Audiotoolbox options not documented

Description (last modified by )
Summary of the bug:
audiotoolboxenc.c defines some options, such as AAC profiles, but none are documented in the big texinfo file. Interaction with global_quality is also undocumented.
How to reproduce:
For all options, navigate to https://ffmpeg.org/ffmpeg-codecs.html.
The built-in help in ffmpeg -h encoder=aac_at is adequate, except that it does not show profiles. This is common to all codecs and should use a different ticket concerning how print_codec() is written. Not that I have the energy to write it.
It looks like aac_at_* options are generic for all AT codecs?

FWIW, refer to https://developer.apple.com/library/archive/technotes/tn2271/_index.html as well as header under AudioToolbox.framework (use Xcode to locate it) for documentation.
