automation: add a QEMU based x86_64 Dom0/DomU test

Introduce a test based on QEMU to run Xen, Dom0 and start a DomU.
This is similar to the existing qemu-alpine-arm64.sh script and test.
The only differences are:
- use Debian's qemu-system-x86_64 (on ARM we build our own)
- use ipxe instead of u-boot and ImageBuilder
