[SYCL] Remove std::runtime_error that dimensionality of cluster, global and local ranges must be same for sycl_ext_codeplay_cuda_cluster_group extension

[dyniols]

This PR removes std::runtime_error that dimensionality of cluster, global and local ranges must be same.

I don't think that this should be restriction. I can't find anything in https://docs.nvidia.com/cuda/cuda-c-programming-guide/#thread-block-clusters

Here is spec for extension: https://github.com/intel/llvm/blob/sycl/sycl/doc/extensions/proposed/sycl_ext_codeplay_cuda_cluster_group.asciidoc

It's idea and I would like to hear your opinions if we can remove that std::runtime_error for cuda cluster?

LGTM

It doesn't seem like the extension mandated this exception and even if it did it shouldn't be an std::runtime_error but some sycl::exception.
