libsvtav1: Add workaround for gop_size == 1
In some versions of libsvtav1, setting intra_period_length to 0
does not produce the intended result (i.e.) all frames produced
are not keyframes.
Instead handle the gop_size == 1 as a special case by setting
the pic_type to EB_AV1_KEY_PICTURE when encoding each frame so
that all the output frames are keyframes.
SVT-AV1 Bug: https://gitlab.com/AOMediaCodec/SVT-AV1/-/issues/2076
Example command: ffmpeg -f lavfi -i testsrc=duration=1:size=64x64:rate=30 -c:v libsvtav1 -g 1 -y test.webm
Before: Only first frame is keyframe, rest are intraonly.
After: All frames are keyframes.
