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().
