The spec says:
 user agents MUST NOT persist device identifiers for sites that are blocked from using cookies, and user agents MUST reset per-origin device identifiers when other persistent storage are cleared.

This seems to induce that we should:
- Not store device IDs if cookies are blocked
- Flush device IDs if Cache Storage, or IDB are flushed, not only cookies.
