All the callers pass in a valid colorspace. SetColorSpace() is the only
caller to CPDF_ColorSpace::GetDefaultColor(). Also adjust that method to
make it harder to use incorrectly.

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().

Ditto with the other ToXXX functions to CPDF_xxx.h.
Shortly, we will want to introduce another variant:
inline std::unique_ptr<CPDF_String> ToString(
std::unique_ptr<CPDF_Object>);
This will require that CPDF_String be complete which is
not the case in the CPDF_Object.h header. Rather than
dragging all the other .h's into it, move these to the
subclass headers. That way, these will be together
when the new form is added.
