This fixes the build with --enable-introspection. I'm not sure why g-ir-scanner seems to parse all public headers in isolation instead of being able take a more limited list of top-level public headers and automatically parse all necessary #include directives but this means we have to special case how we define and undefine __COGL_H_INSIDE__ to subvert the guards we have in place for detecting misuse of the headers.
