[PATCH V2 0/5] Make some DebugLib instance runtime safe

["Gao, Zhichao" <zhichao.gao@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1416

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.

V2:
Fix some typos.
Change the comment of function to meet the Doxygen rule.
