win: improve file delete

This commit unifies the way the files are being deleted by introducing
the `DeleteFiles` function. It refactors existing scripts that are
deleting files to use the new function, to improve their documentation
and increase their safety.

Script changes:

- 'Clear Software Reporter Tool logs':
  - Rename to: 'Clear Google's "Software Reporter Tool" logs'
- 'Clear credentials in Windows Credential Manager':
  - Migrate code to PowerShell, removing the need to delete files.
  - Improve error messages and robustness of the implementation.
- 'Clear Nvidia residual telemetry files':
  - Extract to two scripts for more granularity and better
    documentation:
      1. 'Disable Nvidia telemetry components'
      2. 'Disable Nvidia telemetry drivers'
  - Change the logic so instead of clearing directory contents and
    deleting drivers, it conducts a soft delete for reversibility to
    prioritize user safety.
- 'Remove OneDrive residual files':
  - Improve documentation
- 'Clear primary Windows telemetry file':
  - Rename to 'Clear diagnostics tracking logs'.
  - Add missing file paths seen on modern versions of Windows.
  - Add more documentation.
- 'Clear Windows Update History (`WUAgent`) system logs':
  - Rename to 'Clear Windows update files'.
  - Add more documentation.
- 'Clear Cryptographic Services diagnostic traces':
  - Rename to 'Clear "Cryptographic Services" diagnostic traces'.
  - Add more documentation.

Other changes:

- Improve `DeleteGlob`:
  - Add iteration callbacks for its reusability.
  - Improve its documentation.
  - Make recursion optional.
  - Improve sanity check (verification) logic for given glob when
    granting permissions.
  - Fix granting permissions using wrong variable to find out parent
    directory.
- Improve `IterateGlob`:
  - Use `Get-Item` to get results. This fixes `DeleteDirectory` not
    being able to delete directory itself but just its contents.
  - Introduce and use `recurse` parameter to provide optional recursive
    search logic (to search in subdirectories) using `Get-ChildItem`.
  - Fix wrong PowerShell syntax for `$revert` variable value for
    `revertCode`: replace `true` with `$true`.
  - Order iterated paths based on their length to process the deepest
    item first.
  - Improve handling of missing files with correct/informative outputs
    when granting permissions.
- Improve `SoftDeleteFiles`:
  - Introduce and use `recurse` parameter for explicitness.
  - Fix undefined `$backupFilePath` by replacing it with correct
    `$originalFilePath`.
  - Improve documentation.
- Ensure consistent use of instructive language in code comments.
