avcodec/nvenc: add option to disable all extra SEI data

Browse Source 
With these triggering a lot of crashes recently, an option to globally
disable all of them is added as a tool to work around those crashes in
case the SEI data is not needed by the user.

Also re-enables s12m for hevc_nvenc, since the issue is not specifically
with that, but it affects all SEI data.
