#9727: AAC_AT: broken VBR / missing VBR handle

---------------------------------+---------------------------------------
aac_at needs to accept "-vbr" threshold-specifier to work in VBR mode.
For example, "ffmpeg -h encoder=libfdk_aac" shows the arg "-vbr <int> VBR
mode (1-5)"
However "ffmpeg -h encoder=aac_at" shows no such argument for VBR AAC
using AAC_AT (it's not only "-h" page missing, "-vbr <int> doesn't work")
Moreover, files currently produced with "-c:a aac_at -aac_at_mode 3"
produce CBR instead of VBR.
So simple AAC_AT completely lacks modes 2 (VBR + Cap) and 3 (VBR)
