UEFI标准应用程序模块--SMBIOS的读写

本篇程序参考自博客“UEFI应用与编程–SmBios”https://blog.csdn.net/qyqcs/article/details/79566235
在原博主的基础上进行了一些修改，修改了几处个人觉得有问题的地方。

      //return DMI_SUCCESS;
    }
  }
  *Handle = (UINT16)(-1);
  return EFI_SUCCESS;
}

注意：由于用edk2中的nt32虚拟机编译时找不到shellpkg里面的UefiShellDebug1CommandsLib.h和LibSmbiosView.h，故将其移动edk2\MdePkg\Include\Library目录内。
