    automation: Add arm64 test for running Xen with GICv3
    
    At the moment, all the Arm64 Qemu tests use GICv2 which is the default
    GIC version used by Qemu. Improve the coverage by adding a new test in
    which Qemu will be configured to have GICv3.
    
    Rename host device tree name to "virt.dtb" to be GIC version agnostic.
    Use "gic-version" Qemu option to select the version to use. Unless the
    test variant is set to "gicv3", version 2 will be used.
