Fix crash when ColorSpace references itself directly.
Also fixes any problems with cycles between colorspaces. Past fixes have solved problems with CPDF_DocPageData::GetColorSpace() calling itself and CPDF_DocPageData::GetColorSpace() calling CPDF_ColorSpace::Load() and vice versa. They have not solved CPDF_ColorSpace::Load() calling itself. This CL repurposes the |pVisited| set to ensure CPDF_ColorSpace::Load() does not try to load a colorspace as a dependency of itself and creates |pVisitedLocal| to ensure CPDF_DocPageData::GetColorSpace() does not create a similar circular dependency not involving CPDF_ColorSpace::Load().
