Release: Use pip3 download for Python packages

Replace bundled Python source packages with pip3 download to comply with
Apache Release policy.

- Remove 7 bundled tar.gz packages from gpMgmt/bin/pythonSrc/ext/
- Add download-python-deps target using pip3 download
- Update build targets to depend on download step
- Preserve original compilation logic and --with-pythonsrc-ext functionality
- Update LICENSE, python-dependencies.txt, and Windows build script
- Add .gitignore rules for downloaded files

This maintains the same build behavior while ensuring Apache compliance
by removing third-party packages from source tree.
