Some pointer will be invalid after ExitBootServices, such as protocol pointer, gST, gBS and so on. Disable the functions which used that pointer.
Remove SMM support of UefiDebugLibDebugPortProtocol, UefidebugLibConOut and UefiDebugLibStdErr. Before removing, should change the SMM instance in the dsc file which use them as SMM instance. And null version is safe.
