Move the logic of (re)evaluation of Private DNS

Moves this out of ConnectivityService and into each NetworkMonitor
(where it's more self-contained).

Test: as follows
    - builds, flashes, boots
    - runtest frameworks-net passes
    - manual testing with working and non-working hostnames behaves
      somewhat (but not entirely) as expected, and not always quickly
