Arch Linux

Rebuild for a major CUDA release

Release notes: https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html

Known (potentially) breaking changes for our packages:

- Dropped support for old GPU architectures (before Turing).
- SM101 has been renumbered as SM110 from this release.
- Changed path to CCCL headers: `/opt/cuda/targets/x86_64-linux/include/cccl/{cub,cuda,thrust}/` instead of `/opt/cuda/targets/x86_64-linux/include/{cub,cuda,thrust}/`
- The bundled CUB, libcu++, and Thrust libraries require at least C++17.
- Host compiler changed from `gcc14` to `gcc` (currently 15).

Specific issues are tracked in the todo notes: https://md.archlinux.org/archweb-cuda-13

Instructions:

- Check if there is a hardcoded `cudaver` in the PKGBUILD.
- Some packages might need to be bumped to a new version with CUDA 13 support.
- Use the following list of GPU architectures (in terms of CMake syntax): `-DCMAKE_CUDA_ARCHITECTURES="75;80;86;87;88;89;90;100;103;110;120;121;121-virtual"`
- Release packages to staging.
