[FFmpeg-cvslog] kmsgrab: Add more supported formats

[Mark Thompson]

ffmpeg | branch: master | Mark Thompson <sw at jkqxz.net> | Sat Aug  1 18:57:35 2020 +0100| [6e951d0cf8dcbc98cb45b9a72ed8d9e76f4a2e3f] | committer: Mark Thompson

kmsgrab: Add more supported formats

X2RGB10 tested on both Intel Gen9 and AMD Polaris 11.  NV12 tested on
Intel Gen9 only - since it has multiple planes, this requires GetFB2.

Also add some comments to split the list up a bit.
