Use python-build for package artifacts

Description:

Modernize package artifact creation by replacing direct setup.py invocations
with python -m build. The change uses the standard build frontend while
retaining the existing non-isolated container-build behavior.

Additional information:

Affected modules and functionalities:

• DALI Python wheel packaging in docker/build_helper.sh.
• TensorFlow plugin source-distribution packaging.
• Video plugin source-distribution packaging.

Key points relevant for the review:

• Existing wheel options are forwarded as backend configuration settings.
• --no-isolation preserves use of dependencies installed in the build image.

Tests:

• Existing tests apply
  • build passes
• New tests added
  • Python tests
  • GTests
  • Benchmark

Greptile Summary

This PR modernizes DALI's package artifact creation by replacing direct setup.py invocations with python -m build across the main wheel build, the TF plugin sdist, and the video plugin sdist. The --no-isolation flag preserves the existing behavior of using dependencies already installed in the build image.

• docker/Dockerfile.make_sdist_plugins correctly adds the build package so the video plugin sdist path works.
• plugins/setup.py.in adds egg_info to the command skip-list so that the DALI import guard does not fire during PEP 517 metadata discovery — a necessary correctness fix for the new build frontend.
• docker/Dockerfile_dali_tf was not updated to install build, leaving the TF plugin sdist path broken; make_dali_tf_sdist.sh now calls python -m build but the image only installs setuptools>=70.

Confidence Score: 4/5

Safe to merge for the video-plugin and main-wheel paths; the TF plugin sdist build will fail at runtime because Dockerfile_dali_tf does not install the build package.

Four of the five changed files are handled correctly. The omission is in Dockerfile_dali_tf: the PR explicitly adds build to Dockerfile.make_sdist_plugins for the video-plugin path, but the parallel TF-plugin image only installs setuptools>=70, so python -m build in make_dali_tf_sdist.sh will fail with No module named build.

docker/Dockerfile_dali_tf — needs build added to its pip install line to match what was done in Dockerfile.make_sdist_plugins.

Important Files Changed

Filename	Overview
docker/Dockerfile_dali_tf	Installs setuptools>=70 but omits the new build package dependency required by make_dali_tf_sdist.sh — TF plugin sdist build will fail.
docker/build_helper.sh	Replaces python setup.py bdist_wheel with python -m build --wheel --no-isolation; options correctly split between --global-option and --build-option after previous review fix.
docker/Dockerfile.make_sdist_plugins	Correctly adds the build package alongside existing setuptools>=70 and scikit-build to support python -m build in the video plugin path.
dali_tf_plugin/make_dali_tf_sdist.sh	Switches TF plugin sdist creation from python setup.py sdist to python -m build --sdist --no-isolation; correct invocation, but depends on build being installed in the container image.
plugins/setup.py.in	Adds egg_info to the skip-list alongside sdist so the DALI import/version guard does not run when build calls setup.py egg_info during PEP 517 metadata discovery.
plugins/video/CMakeLists.txt	Replaces setup.py sdist with python -m build --sdist --no-isolation in the CMake post-build command for the video plugin.
