[PATCH V4 01/17] MdePkg/DebugLib.h: Add new APIs for DebugLib

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

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1395

Add new APIs DebugVPrint and DebugBPrint prototype
definition in the DebugLib header file. These APIs
would expose a print routine with VaList parameter
and BaseList parameter.
