[Patch][edk2-platforms/devel-MinnowBoard3-UDK2017] Add option /m to enable multiple thread build

[Yonghong Zhu <yonghong.zhu@intel.com>]

current in windows it takes ~10 minutes to build a image, so we add
/m option to use EDK II build tool's multiple thread build function,
it can save about half build time.
