This checkin addresses the compatibility issue of passing arguments of type VA_LIST between components. The type VA_LIST is mapped onto the compiler specific implementation of varargs. As a result, modules build with different compilers may not use the same VA_LIST structure. The solution to this issue is to define a new type called BASE_LIST that is a compiler independent method of passing varargs between modules.

Add BASE_LIST type to Base.h
Add BAS_ARG() macro to Base.h
Add 4 functions to PrintLib.h that use BASE_LIST.
Change ReportStatsuCodeExtractDebugInfo() from ReportStatusCodeLib.h to take a BASE_LIST argument instead of a VA_LIST argument
Add the 4 new functions to BasePrintLib implementation that use BASE_LIST
Update BaseReportStatusCodeLib implementation of ReportStatsuCodeExtractDebugInfo() to use a BASE_LIST argument instead of a VA_LIST argument
