avcodec/libdav1d: export decoder frame delay

Browse Source 
As this is an AV_CODEC_CAP_OTHER_THREADS decoder, threading is handled by the
underlying library. In this case, the frame delay is calculated by libdav1d
based on the values from avctx->thread_count and the private max_frame_delay
option.
Export said delay reported by the library in AVCodecContext.delay
