Now we have virtio-gpu Vulkan support lets add a test for it.
Currently this is using images build by buildroot:

v2
- use decorator for has_cmd(zstd)
- move set_machine/require_accelerator to top of test
- un-handled->unhandled
- drop extra - from --snapshot
- drop unneeded virtualization=3Don
- only show 1s of each scene
- fix long lines
