This CL introduces a new public API function, FPDFBookmark_GetColor, which allows emedders to retrieve the RGB color components of a PDF outline item (bookmark). To support this, this CL adds the CPDF_Bookmark::GetColor() method to get values from the optional "/C" array from the underlying bookmark dictionary. The API validates that the RGB color components are present, correctly formed, and conform to the PDF specification limits (values between 0.0 and 1.0).
