Create weekly builds with python wrapping for ITK and its modules, and submit them to pypi

[aylward]

Description

The release schedule for ITK is good, but given the rapid pace at which ITK continues to evolve/improve, it would be helpful if the community had access to recent (weekly) builds of ITK for python on PyPi.

Expected behavior

A github "schedule" action triggers building ITK and its modules and pushing to pypi. For more info on schedule action triggers, see
https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule

The weekly releases could go under the PyPi project "itk-weekly".

Actual behavior

The release of external projects that depend on recent changes to ITK are delayed until a RC is produced - and RC's are not produced on a consistent schedule, which further complicates external development, dependencies, and releases.

Additional Information

For example, see

Good idea. We can get there via the following steps:

• 1. Finalize the Clang module support so wrapping with all the options enabled can occur with the GitHub Action runners: Clang module support for internal builds #3093
• 2. Switch the Windows and Linux builds to be driven by Clang
• 3. Enable the GitHub Actions on CI and weekly to build, deploy the builds to GitHub Releases, deploy to PyPI
