avcodec/amfenc: add smart access video option

Browse Source 
This commit adds option for enabling SmartAccess Video (SAV)
in AMF encoders. SAV is an AMD hardware-specific feature which
enables the parallelization of encode and decode streams across
multiple Video Codec Engine (VCN) hardware instances.
