Move virtual graphics drivers from linux-modules-extra to linux-
modules

Bug description:
[SRU justification]
Impact: We split the drivers into linux-modules and linux-modules-extra. The
latter is only included for setups geared towards real hardware (desktops,
laptops). For VM guests the recommended setup is to use linux-virtual which
does not include linux-modules-extra but also does not depend on other
packages, like linux-firmware.
We already include most VM related drivers in the linux-modules package and
vboxvideo (since 21.10/Impish). So it makes sense to include the missing ones.
Fix: Move the following modules from linux-modules-extra into linux-modules:
- bochs-drm (though a bit aged, this was the predecessor of qemu)
- cirrus (this is a standard emulated gfx card, might not give the best
performance but better than nothing)
- virtio-gpu (KVM)
- vmwgfx (VMWare)
- drm-xen-front (Xen)
Testcase: Check linux-modules for the mentioned modules.
Regression Potential: There should be no change noticeable. Users with
linux-modules-extra installed will see no difference and those without
have additional drivers. Maybe this shows as moving from low-
resolution graphics to higher ones which maybe perform less.
--- Original Description ---
Kernel: Ubuntu 5.13.0-28.31-generic 5.13.19
Distribution: Ubuntu 21.10 (impish)
I run an Ubuntu desktop as a VMWare virtual machine client.
The linux-modules-extra-${VERSION}-generic package contains
kernel/drivers/gpu/drm/vmwgfx/vmwgfx.ko, so at the moment I need to
keep it installed and updated. The only way to do so conveniently is
to install linux-image-generic, which also pulls in linux-firmware,
which is ~760MB installed.
If vmwgfx was moved from linux-modules-extra to linux-modules, I could
use linux-image-virtual instead of linux-image-generic, remove linux-
firmware, linux-modules-extra, and the microcode packages, saving
substantial disk space and bandwidth.
Other virtual graphics drivers in linux-modules-extra that might be
worth moving are:
kernel/drivers/gpu/drm/bochs/bochs-drm.ko
kernel/drivers/gpu/drm/virtio/virtio-gpu.ko
kernel/drivers/gpu/drm/xen/drm_xen_front.ko
Thank you for your consideration.
Note: Edited significantly in response to
https://lists.ubuntu.com/archives/kernel-
team/2022-February/128103.html and
https://lists.ubuntu.com/archives/kernel-
team/2022-February/128104.html to better reflect the underlying
problem and solution.
P.S. There are three other drivers in linux-modules-extra that seem
VMWare-related, but they are not in use in my VM and I don't know
whether they are in common enough use to justify moving them to linux-
modules. I have listed them here for completeness.
kernel/drivers/net/vsockmon.ko
kernel/drivers/ptp/ptp_vmw.ko
