Nick Khyl 4d68493144 health: avoid publishing health.Change when warnable visibility remains unchanged

Warnables with a non-zero TimeToVisible are only published on the eventbus when
they remain unhealthy long enough to become visible.

However, we still publish a health.Change when a warning that was never visible
(and was never published to the eventbus) becomes healthy.

This PR fixes that and reduces churn when there is no actual state change. In
particular, it avoids unnecessary IPN bus notifications sent to GUI/CLI clients,
captive portal detection, etc.

Updates tailscale/corp#39759 (noticed while working on it)
