[SRU J/I/F] Move some DRM modules from modules-extra to modules

[Stefan Bader]

Some users run a desktop environment inside VM guests. Those would
benefit a lot from having DRM drivers (especially for the paravirt
ones). For Impish and Jammy we already include vboxvideo. There is
also tegra-drm (which looks to be Arm related) and ast. The latter
I believe is something used on newer IPMI supporting boards.

Beside of the obvious ones, I would also include cirrus because that
is the most basic emulated graphics card everyone has. Together with
llvm-pipe it at least allows some moderate desktop experience.

This is purely moving stuff from extra to the basic modules. All drivers
are already built as modules.
