win: improve disabling update healing #272

This commit strengthens user control over the Windows Update Medic
Service (`WaaSMedicSvc`) and related components. These changes aim to
provide users with more control over Windows updates and telemetry data
shared with Microsoft, addressing privacy concerns.

Updates include:

- Soft deletion of various Windows Update Medic Service files and
  remediation files to prevent automatic re-enabling of Windows updates.
- Termination of `upfc.exe` to stop it from reactivating Windows Update
  Medic Service, thereby allowing users to maintain their desired update
  settings.
- Improving documentation with cautionary notes to guide users through
  poential impacts of these changes on system stability and update
  integrity.
- Including rationale behind the exclusion of `sedsvc`.
- Better documentation and output messages of `DisableService` function.
