avcodec/libsvt_av1: remove forced-idr option

This option is directly copy-pasted from the SVT1-HEVC wrapper and has
no place in the options for an AV1 encoder.

AV1 has no H.264/5 IDR frames nor anything like them.
All this option does is change all real keyframes to an intra-only
AV1 frame, which is not seekable. Hence, any streams encoded with
this option enabled will not be seekable.
