From: opencv_contrib upstream (in master and 5.0.0), backported to 4.12.0/4.13.0
Subject: cudev ptr2d/zip.hpp: select _CCCL_*_NAMESPACE_CUDA_STD on CUDA 13.2+

CUDA 13.2 reorganised CCCL, so the unconditional _LIBCUDACXX_BEGIN_NAMESPACE_STD
used to specialise std::tuple_size / tuple_element for ZipPtr no longer compiles
(the build dies at the first CUDA TU).  Guard the namespace macros exactly as
upstream master / 5.0.0 do.  Inert on CUDA < 13.2 and without cuda.
