Vignesh Venkatasubramanian ab05e9a7f2 avcodec/libaomenc: Add parameter for avif single image encoding 
Add a parameter to libaom-av1 encoder to enforce some of the single
image constraints in the AV1 encoder. Setting this flag will limit
the encoder to producing exactly one frame and the sequence header
that is produced by the encoder will be conformant to the AVIF
specification [1].

Part of Fixing Trac ticket #7621
