    automation: arm64: Create test jobs for testing static shared memory on qemu
    
    Create 2 new test jobs, called 
qemu-smoke-dom0less-arm64-gcc-static-shared-mem
    and qemu-smoke-dom0less-arm64-gcc-debug-static-shared-mem.
    
    Adjust qemu-smoke-dom0less-arm64.sh script to accomodate the static
    shared memory test as a new test variant. The test variant is determined
    based on the first argument passed to the script. For testing static
    shared memory, the argument is 'static-shared-mem'.
    
    The test configures two dom0less DOMUs with a static shared memory
    region and adds a check in the init script.
    
    The check consists in comparing the contents of the 
/proc/device-tree/reserved-memory
    xen-shmem entry with the static shared memory range and id with which
    DOMUs were configured. If the memory layout is correct, a message gets
    printed by DOMU.
    
    At the end of the qemu run, the script searches for the specific message
    in the logs and fails if not found.
