    automation: Use custom build jobs when extra config options are needed
    
    Currently, all the arm64 defconfig build jobs, regardless of the
    container used, end up building Xen with the extra config options
    specified in the main build script (e.g. CONFIG_EXPERT,
    CONFIG_STATIC_MEMORY). Because these options are only needed for
    specific test jobs, the current behavior of the CI is incorrect
    as we add the extra options to all the defconfig builds. This means
    that on arm64 there is not a single job performing proper defconfig build.
    
    To fix this issue, add custom build jobs each time there is a need for
    building Xen with additional config options. Introduce EXTRA_XEN_CONFIG
    variable to be used by these jobs to store the required options. This
    variable will be then read by the main build script to modify the .config
    file. This will also help users to understand what is needed to run specific
    test.
