    automation: arm64: Create a test job for testing static allocation on qemu
    
    Enable CONFIG_STATIC_MEMORY in the existing arm64 build.
    
    Create a new test job, called qemu-smoke-arm64-gcc-staticmem.
    
    Adjust qemu-smoke-arm64.sh script to accomodate the static memory test as a
    new test variant. The test variant is determined based on the first argument
    passed to the script. For testing static memory, the argument is 
'static-mem'.
    
    The test configures DOM1 with a static memory region and adds a check in the
    init script.
    The check consists in comparing the contents of the /proc/device-tree
    memory entry with the static memory range with which DOM1 was configured.
    If the memory layout is correct, a message gets printed by DOM1.
    
    At the end of the qemu run, the script searches for the specific message
    in the logs and fails if not found.
