QEMU with VirtIO GPU Vulkan Support

With its latest reales qemu added the Venus patches so that virtio-gpu now support venus encapsulation for vulkan. This is one more piece to the puzzle towards full Vulkan support.

An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for VirtIO-GPU with a local development environment. Following up on the outdated write up, this is how its done today.

Let's start with the brief description of the projects mentioned in the post & extend them:

	# Use this in a situation where you want a headless Linux box with multiple GPU boards but no desktop environment
	# Fake EDID convinces drivers that a monitor is connected
	# Use any EDID binary file
	# To start a fake X server make a systemd file with something like:
	# ExecStart=/usr/bin/tcsh -c 'xinit /opt/set-gpu-fans/setfanspeed.sh -- :0 -once -config /opt/set-gpu-fans/xorg.rob'
	# See other gist for fan setting script : https://gist.github.com/RobDeBagel/a960c2b157256c162220e60300529cf0
