win: centralize, improve Defender data collection

This commit reorganizes scripts related to disabling Defender's data
collection and telemetry into a dedicated category. This improves
usability for users focused on enhancing privacy without needing to
understand technical details of each option.

Changes:

- Create "Disable Defender data collection" category
- Move related scripts under new category
- Improve script documentation and naming
- Add alternate configurations to some scripts
- Fix extended cloud check feature being enabled instead of disabled
- Update script recommendations to 'Strict'
