    tools/firmware/ovmf: Use OvmfXen platform file is exist
    
    A platform introduced in EDK II named OvmfXen is now the one to use for
    Xen instead of OvmfX64. It comes with PVH support.
    
    Also, the Xen support in OvmfX64 is deprecated,
        "deprecation notice: *dynamic* multi-VMM (QEMU vs. Xen) support in 
OvmfPkg"
