Process new syntax in the DEC file that specifies
information that can only be used by modules within
the package. When modules outside the packages attempt
to use this content, the EDK II build system must
break with an error regarding content not found.
The four sections, Includes, Ppis, Guids and Protocols
headers will be the keyword, Private, following the
architecture modifier. If Private is not present, then
the content is usable by modules outside the package.
