[Security Solution][Endpoint] Fix Response Console not displaying the platform icon for non-Windows hosts when opened from an alert (#188030)

## Summary

- Fixes `useAlertResponseActionsSupport()` hook so that the OS platform
is retrieved from the alert's `host.os.type`
- Note: tests already exist to validate this, however, the mocks were
also incorrectly typed. Those are now corrected as well.
