[Merge to XFA] Revert "Revert "Add type cast definitions for CPDF_Dictionary.""
This reverts commit 937840e1722d1f2b77d80575d6e710d760662c9c.
Add type cast definitions for CPDF_Dictionary.
This CL adds ToCPDFDictionary type definitions and updates one file to use
instead of straight casts. I had to fix two places where we'd casted off the
constness of the original pointer.
