lavc/vaapi: Declare support for decoding 8bit 4:4:4 content

Now that we have a combination of capable hardware (new enough Intel)
and a mutually understood format ("AYUV"), we can declare support for
decoding 8bit 4:4:4 content via VAAPI.

This requires listing AYUV as a supported format, and then adding VAAPI
as a supported hwaccel for the relevant codecs (HEVC and VP9). I also
had to add VP9Profile1 to the set of supported profiles for VAAPI as it
was never relevant before.
