Rename CPDF_Object::Type enumerators with k prefixes

This was originally motivated by Clang's newly enhanced -Wshadow
warning, which complained about BOOLEAN shadowing a BOOLEAN typedef
in winnt.h. The warning has since been changed to not fire on enums
shadowing types, but it was suggested that this kind of naming change
was desirable anyway.
