Understand whether weston on Wayland can replace Xvfb

[sxa]

CentOS Stream 10 has chosen to remove all support for xorg and that includes xvfb.
weston is a potential alternative, but while it's available in EPEL10 it does not install properly due to broken dependencies.

Assuming this is the first notable distribution to have dropped all the xorg packages, and they won't add it back in, we should investigate alternatives in order to be able to continue to run the AQA tests that expect a display to be available.

(FYI @judovana in case anyone in your team has already investigated this)
