When building non-depends with internal ffmpeg we currently hardcode ffmpeg options.
This PR allows to at least disable vaapi and vdpau in ffmpeg.
Description
Motivation and Context
building with internal ffmpeg fails when vaapi or vdpau is disabled and the needed libs are missing, or ffmpeg still builds with support for both hw accels.
How Has This Been Tested?
quick build test on linux.
I'm a little bit wary about the reordering of dependency checking, so this needs some testing
