#5894: Wrong -auto-alt-ref option type

------------------------------------+--------------------------------------
 libvpx API allows 0, 1 and 2 values for `enable_auto_alt_ref` option in
 case of VP9, see
 [[https://chromium.googlesource.com/webm/libvpx/+/v1.6.0/vp9/vp9_cx_iface.c#257|vp9_cx_iface.c]].
 But ffmpeg uses `AV_OPT_TYPE_BOOL` for it, thus making impossible to
 enable `multi_arf_allowed` mode.
