Fix assert definition for NVHPC due to constexpr issues (NVIDIA#3418)

NVHPC cannot decide at compile time where the code would run so _CCCL_ASSERT within a constexpr function breaks it.

Fix this by always using the host definition which should also work on device.

Fixes NVIDIA#3411

Replace and deprecate thrust::cuda_cub::terminate (NVIDIA#3421)

`std::linalg` accessors and `transposed_layout` (NVIDIA#2962)

Add round up/down to multiple (NVIDIA#3234)

[FEA]: Introduce Python module with CCCL headers (NVIDIA#3201)

* Add cccl/python/cuda_cccl directory and use from cuda_parallel, cuda_cooperative

* Run `copy_cccl_headers_to_aude_include()` before `setup()`

* Create python/cuda_cccl/cuda/_include/__init__.py, then simply import cuda._include to find the include path.

* Add cuda.cccl._version exactly as for cuda.cooperative and cuda.parallel

* Bug fix: cuda/_include only exists after shutil.copytree() ran.

* Use `f"cuda-cccl @ file://{cccl_path}/python/cuda_cccl"` in setup.py

* Remove CustomBuildCommand, CustomWheelBuild in cuda_parallel/setup.py (they are equivalent to the default functions)

* Replace := operator (needs Python 3.8+)

* Fix oversights: remove `pip3 install ./cuda_cccl` lines from README.md

* Restore original README.md: `pip3 install -e` now works on first pass.

* cuda_cccl/README.md: FOR INTERNAL USE ONLY

* Remove `$pymajor.$pyminor.` prefix in cuda_cccl _version.py (as suggested under NVIDIA#3201 (comment))

Command used: ci/update_version.sh 2 8 0

* Modernize pyproject.toml, setup.py

Trigger for this change:

* NVIDIA#3201 (comment)

* NVIDIA#3201 (comment)

* Install CCCL headers under cuda.cccl.include

Trigger for this change:

* NVIDIA#3201 (comment)

Unexpected accidental discovery: cuda.cooperative unit tests pass without CCCL headers entirely.

* Factor out cuda_cccl/cuda/cccl/include_paths.py

* Reuse cuda_cccl/cuda/cccl/include_paths.py from cuda_cooperative

* Add missing Copyright notice.

* Add missing __init__.py (cuda.cccl)

* Add `"cuda.cccl"` to `autodoc.mock_imports`

* Move cuda.cccl.include_paths into function where it is used. (Attempt to resolve Build and Verify Docs failure.)

* Add # TODO: move this to a module-level import

* Modernize cuda_cooperative/pyproject.toml, setup.py

* Convert cuda_cooperative to use hatchling as build backend.

* Revert "Convert cuda_cooperative to use hatchling as build backend."

This reverts commit 61637d6.

* Move numpy from [build-system] requires -> [project] dependencies

* Move pyproject.toml [project] dependencies -> setup.py install_requires, to be able to use CCCL_PATH

* Remove copy_license() and use license_files=["../../LICENSE"] instead.

* Further modernize cuda_cccl/setup.py to use pathlib

* Trivial simplifications in cuda_cccl/pyproject.toml

* Further simplify cuda_cccl/pyproject.toml, setup.py: remove inconsequential code

* Make cuda_cooperative/pyproject.toml more similar to cuda_cccl/pyproject.toml

* Add taplo-pre-commit to .pre-commit-config.yaml

* taplo-pre-commit auto-fixes

* Use pathlib in cuda_cooperative/setup.py

* CCCL_PYTHON_PATH in cuda_cooperative/setup.py

* Modernize cuda_parallel/pyproject.toml, setup.py

* Use pathlib in cuda_parallel/setup.py

* Add `# TOML lint & format` comment.

* Replace MANIFEST.in with `[tool.setuptools.package-data]` section in pyproject.toml

* Use pathlib in cuda/cccl/include_paths.py

* pre-commit autoupdate (EXCEPT clang-format, which was manually restored)

* Fixes after git merge main

* Resolve warning: AttributeError: '_Reduce' object has no attribute 'build_result'

* Move `copy_cccl_headers_to_cuda_cccl_include()` functionality to `class CustomBuildPy`

* Introduce cuda_cooperative/constraints.txt

* Also add cuda_parallel/constraints.txt

* Add `--constraint constraints.txt` in ci/test_python.sh

* Update Copyright dates

* Switch to https://github.com/ComPWA/taplo-pre-commit (the other repo has been archived by the owner on Jul 1, 2024)

For completeness: The other repo took a long time to install into the pre-commit cache; so long it lead to timeouts in the CCCL CI.

* Remove unused cuda_parallel jinja2 dependency (noticed by chance).

* Remove constraints.txt files, advertise running `pip install cuda-cccl` first instead.

* Make cuda_cooperative, cuda_parallel testing completely independent.

* Run only test_python.sh [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Try using another runner (because V100 runners seem to be stuck) [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Fix sign-compare warning (NVIDIA#3408) [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Revert "Try using another runner (because V100 runners seem to be stuck) [skip-rapids][skip-matx][skip-docs][skip-vdc]"

This reverts commit ea33a21.

Error message: NVIDIA#3201 (comment)

* Try using A100 runner (because V100 runners still seem to be stuck) [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Also show cuda-cooperative site-packages, cuda-parallel site-packages (after pip install) [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Try using l4 runner (because V100 runners still seem to be stuck) [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Restore original ci/matrix.yaml [skip-rapids]

* Use for loop in test_python.sh to avoid code duplication.

* Run only test_python.sh [skip-rapids][skip-matx][skip-docs][skip-vdc][skip pre-commit.ci]

* Comment out taplo-lint in pre-commit config [skip-rapids][skip-matx][skip-docs][skip-vdc]

* Revert "Run only test_python.sh [skip-rapids][skip-matx][skip-docs][skip-vdc][skip pre-commit.ci]"

This reverts commit ec206fd.

* Implement suggestion by @shwina (NVIDIA#3201 (review))

* Address feedback by @leofang
