Add missing operator<() to CFX_RetainPtr.

Use std::less<>() rather than a direct ptr1 < ptr2 comparison to
be strictly correct in face of unspecified behaviour when ptr1 and
ptr2 don't point within the same "object" (e.g. segment of memory
on a brain-dead segmented architecture).

This will allow their use as keys in maps.
