    automation: Add a static memory allocation test on arm32
    
    Add a new test job qemu-smoke-dom0less-arm32-gcc-staticmem in debug
    and non-debug variant that will execute qemu-smoke-dom0less-arm32.sh
    script to test static memory allocation feature. The test case itself
    is directly taken from dom0less arm64 testing.
    
    Populate build jobs to compile Xen with config options necessary to
    enable static memory feature. Populate test jobs passing "static-mem"
    as a test variant. The test configures domU with a static memory region
    (direct-mapped) and adds a check using /proc/iomem to determine the
    memory region marked as "System RAM".
