MdePkg/Include: Update Base.h to improve C++ compatibility
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4134 * Map NULL to nullptr or __null when c++ compiler is used. * Map STATIC_ASSERT to static_assert when a c++ compiler is used. * Typecast RETURN_SUCCESS to type RETURN_STATUS to match type used by all return error/warning status codes. C++ has stricter type checking and found this inconsistency.
