Replace the static format whitelist with a device-probed table and add 4:4:4 (VUYX/XV30/XV36/XV48) and 4:2:0 12/16-bit (P012/P016) surfaces to both the zero-copy and copy mapper paths. The packed YUV formats can't be decomposed by ra_get_imgfmt_desc(), so they are viewed as a single RGBA texture and the swizzle is recovered from the imgfmt descriptor, which only works with --vo=gpu-next.

Currently, doesn't change much. But this change enables 12-bit decoding, added by https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23553. Also for the future where HEVC 444 might be added. |

What about 4:2:2? Intel and NV Blackwell indeed support them. |

It would be supported too, but it's not exposed in ffmpeg, there needed to be changes. |
