fix cuda 13.3 errors

[jmackay2]

Upgrading to CUDA 13.3 included an update of thrust. This resulted in the following build failures in the cuda module:

pcl/cuda/common/include/pcl/cuda/point_cloud.h(287)
namespace "thrust" has no member "tuple"

pcl/cuda/common/include/pcl/cuda/point_cloud.h(301)
namespace "thrust" has no member "make_tuple"

pcl/cuda/features/include/pcl/cuda/features/normal_3d_kernels.h(172)
namespace "thrust" has no member "get"

...

This fixes the issue by switching to use cuda::std instead of thrust when there is a newer version of thrust.

Testing

This was tested by building on Ubuntu 24.04 with both CUDA 12.9 and 13.3.

Thank you for the fix. However, I have to say I am a bit hesitant to put these three function into the thrust namespace. pcl/cuda/thrust.h is included by pcl/cuda/point_cloud.h, which is in turn included by several other files. Im am worried that there might be problems if a user project uses PCL and some other library which also uses thrust. I guess the less risky fix would be to replace thrust::tuple, thrust::make_tuple, and thrust::get where they are used within PCL, with a preprocessor check. Or alternatively, something like this:

#if THRUST_MAJOR_VERSION >= 3
#include <cuda/std/tuple>
namespace pcl_thrust {
    using ::cuda::std::tuple;
    using ::cuda::std::make_tuple;
    using ::cuda::std::get;
}
#else
namespace pcl_thrust {
    using ::thrust::tuple;
    using ::thrust::make_tuple;
    using ::thrust::get;
}
#endif

And change thrust::tuple to pcl_thrust::tuple etc. within PCL. What do you think?

Thanks @mvieth for the comments. I went through the updated thrust files today and realized that everything was actually handled properly in the thrust/tuple.h file. Including this file fixes the issue and works across different versions of thrust properly. This seems like the right way to fix the issue. I think this fixes the issues you pointed out with the previous approach I took.
