{Build} Packaging - Drop Python 3.9 support

Summary:
Explanation:
Python 3.9 reached end of life in October 2025 and no longer receives security fixes, so `projectaria-tools` no longer builds or ships wheels for it. The minimum supported version becomes 3.10, which is already the floor on macOS ARM64 and Windows.

Changes:
- update workflow
- update documentation
- update setup.py (pywheel python minimum version)
