cuda.parallel: invoke pytest directly rather than via `python -m pytest` #3523

Description

The problem

Recent cuda.parallel tests on CI have been failing:

Click to see what the failure looks like

_________________________________ ERROR collecting tests/test_reduce.py _________________________________
ImportError while importing test module '/home/coder/cccl/python/cuda_parallel/tests/test_reduce.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/lib/python3.10/importlib/__init__.py:126: in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
tests/test_reduce.py:13: in <module>

cuda/parallel/experimental/_bindings.py:10: in <module>
    from cuda.cccl import get_include_paths  # type: ignore[import-not-found]
E   ModuleNotFoundError: No module named 'cuda.cccl'

Why is this happening?

In test_python.sh, we invoke pytest as follows:

run_command "🚀  Pytest ${module}" python -m pytest -v ./tests

Note that the working directory for the invocation above is cuda_parallel directory, which contains a subdirectory named cuda.

According to the pytest docs, invoking pytest in this way adds the working directory (cuda_parallel) to the sys.path. This means that imports of subpackages like cuda.cccl will be attempted from the cuda_parallel directory, rather than the site-packages (which is where cuda.cccl lives). This is the problem - cuda_parallel/cuda doesn't contain the cccl subpackage.

How to fix it?

There are a few possible solutions here:

Invoke pytest directly rather than via python -m pytest. This explicitly does not add the current working directory to the Python search path.
Invoke pytest (in whatever way) from a directory other than cuda_parallel - e.g., cd .. && python -m pytest cuda_parallel/tests. This way imports of cuda.cccl will still be resolved from the site-packages directory.
Reorganize to src layout rather than flat layout.. This way the cuda_parallel directory will not contain a cuda subdirectory.

I felt (1) was the simplest solution. I believe that cuda.core also needed to recently make a similar change.

Yeah in cuda-python we teach QA about the difference between pytest and python -m pytest:

@shwina do you know what change led to the failure? When/why did it stop working? — But I think this is definitely a good change regardless.

I tried to dig into this but I could find nothing significant that has changed. We're not picking up any new versions of our dependencies. I have no idea how we have not seen this before.
