REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1416 After ExitBootServices, some pointer would be invalid such as the Protocol pointer and gBS. The function depend on those should be prevent. So disable the related function while after ExitBootServices. Change the gBS to a internal one, because there will be a cycle consume between UefiBootServicesTableLib and DebugLib due to the library constructors. Also remove the SMM support for this instance.
