aacenc: use the new function for setting special band scalefactor indices

This commit enables the function added with commit 7c10b87 and uses that
new function for setting any special scalefactor indices. This commit does
not change the behaviour of the encoder since no bands are being marked as
either NOISE_BT(due to the previous PNS implementation removed in the
previous commit) or INTENSITY_BT2/INTENSITY_BT.

avcodec/nvenc: Add support for H.264 High 444 Predictive encoding

Newer versions of the nvenc hardware support The High 444 Predictive profile
of H.264, and can also do lossless encoding under this profile if desired.

This change introduces support for the profile, and exposes the appropriate
presets for requesting lossless encoding.

I tested lossless by generating a baseline sample with testsrc converted
to raw yuv444p, then encoded the sample with nvenc, then did a framemd5
comparision of both the raw video and the nvenc encode. The framemd5
reports were identical.
