win: fix Win 11 Windows Security app removal #195

This commit fixes the issue of Windows Security app not being removed in
Windows 11. It addresses the problem by extending the app uninstallation
process to cover the new app package specific to Windows 11. It improves
the overall design of templated functions for store app removal to
implement the fix.

- Improve Windows Security removal script:
  - Add support for removing `Microsoft.SecHealthUI` in Windows 11.
  - Revise script documentation for clarity and correct typos.
- Redesign uninstallion of Store apps:
  - Change `UninstallSystemApp` to `UninstallNonRemovableStoreApp` for
    wider usage. This change is due to `Microsoft.SecHealthUI` being
    non-removable yet not a system app.
  - Refactor app data cleanup into two distinct functions
    (`ClearStoreAppDataBeforeUninstallation` and
    `ClearStoreAppDataAfterUninstallation`) for better clarity and
    maintainability. This also helps in testing by allowing easier
    reordering of operations.
  - Seperate between simple non-removable app uninstallation and
    uninstallation with cleanup in separate functions, highlighting that
    the latter is more invasive and should be used cautiously. This
    addresses permission issues encountered with `SecHealthUI` app
    removal during cleanup on Windows 11.
  - Separate uninstalling app and uninstalling app with cleanup to
    different functions, document that cleanup should no longer be
    prefered as it's invasive and too aggresive. Cleanup logic
    introduces permission issues/errors for `SecHealthUI` in Windows 11.
  - Extend app soft-deletion to include the default Windows app folder,
    this ensures that the cleanup covers any kind of Store apps (not
    only system apps).
