avcodec: add AV1 hardware accelerated decoder

Multimedia / FFmpeg - Fei Wang [intel.com] - 12 September 2020 16:08 UTC

This AV1 decoder is currently only used for hardware accelerated decoding. It can be extended into a native decoder in the future, so set its name to "av1" and temporarily give it the lowest priority in the codec list.
