    xen/Kconfig: introduce HAS_STATIC_MEMORY
    
    Introduce HAS_STATIC_MEMORY so that STATIC_MEMORY can be enabled or
    disabled on a per-architecture basis. ARM selects the new flag; RISC-V
    does not, so CONFIG_STATIC_MEMORY is unavailable on RISC-V and
    randconfig builds no longer require an explicit STATIC_MEMORY=n override
    to avoid a compilation error.
