Update to non-deprecated macOS runners (macos-15-large and macos-latest)

GitHub is deprecating macos-13 runners:
- Deprecation begins: September 22, 2025
- Full retirement: December 8, 2025
- Reference: actions/runner-images#13046

Changes:
- Replace macos-13 with macos-15-large (Intel x86_64, supported until Aug 2027)
- Add macos-latest (ARM64) for Apple Silicon support
- Update both build_wheels and test_wheels jobs
- Now building wheels for 3 platforms: Linux x86_64, macOS Intel, macOS ARM

Benefits:
- Future-proof CI/CD (no deprecation warnings)
- Support for both Intel and Apple Silicon Macs
- Users get native wheels for their architecture
