Save dismissed state for legacy voicemail notification

TelephonyManager will resend legacy voicemail notifications during connectivity changes with a "is_refresh" flag. Such notifications has already been shown before and should not alert the user. Previously the notification will be set to onlyAlertOnce, but if the user dismissed it it will be shown again.

In this CL, if the notification is dismissed, the state will be persisted and the notification will not be shown again. The state will be cleared when a new voicemail arrived and the user will be notified again. Since telephony sends is_refresh=false during boot up, the state will also be cleared with a reboot.
