kmsgrab pixel formats missing DRM_FORMAT_ARGB2101010 and others

[jean]

Summary of the bug: When a DRM plane is using certain formats found in modern wayland compositors, kmsgrab will fail to recognize the pixel format and refuse to start.
How to reproduce:
On KDE Plasma wayland 5.26.5:

% sudo ffmpeg -f kmsgrab -i - output.mp4
ffmpeg version N-109841-ge3bbf5c17d Copyright (c) 2000-2023 the FFmpeg developers
  built with gcc 12.2.1 (GCC) 20230201
...
[kmsgrab @ 0x559fd171b2c0] Framebuffer pixel format 30335241 is not a known supported format.

This was tested on Arch Linux.

The specific pixfmt missing in my case was DRM_FORMAT_ARGB2101010, though it's possible other formats of this classification (32 bpp format with 10 bits per color and 2 bits of alpha) might also be used and would also need to be added.

DRM format 30334241 is also missing.

The command bellow fails in Wayland and runs fine under X11:

$ ffmpeg -device /dev/dri/card1 -f kmsgrab -i '-' -vf 'hwmap=derive_device=vaapi,crop=1280:720:600:10,scale_vaapi=1280:720:nv12' -c:v h264_vaapi test-out.mp4
