Update dump_devinfo for raw discovery json and common redactors (#1358)

This PR does a few related things to dump_devinfo:

- Store the raw discovery result in the fixture.
- Consolidate redaction logic so it's not duplicated in dump_devinfo.
- Update existing fixtures to:
  - Store raw discovery result under `result`
  - Use `SCRUBBED_CHILD_DEVICE_ID` everywhere
  - Have correct values as per the consolidated redactors.
