AV1 computational performance and quality has improved greatly over the least few years and I find that it has become a viable free alternative to the encumbered H.264 for my use cases. This patch adds support for graphics/ffmpeg for svt-av1, which we already have in ports as multimedia/svt-av1.

Tested on amd64 with current svt-av1 and Brad Smith's 3.1.2 patch sent to ports@ last week, but would appreciate testing on other platforms. You can for example use:

	ffmpeg -f lavfi -t 17 -i testsrc=size=1920x1080 -c:v libsvtav1 /tmp/svtav1test.webm
