    automation: Add support for using XTF for arm64 testing
    
    Introduce support for using XTF on Arm to perform low-level testing.
    For the purpose of the CI testing, let's use the fork [1] from upstream
    XTF with implemented support for arm64 (the upstream XTF only supports
    x86).
    
    Add a new script under automation/scripts to be used by the CI XTF test
    jobs to perform the following tasks:
     - Compiling XTF,
     - Generating u-boot script using ImageBuilder,
     - Running Xen with XTF as domU in pure dom0less configuration using Qemu,
     - Checking test result.
    
    The script takes the name of the XTF test to run as a first parameter.
