Don't trigger Phishguard pings if we cannot compute URL reputation.

e.g.: private URL/IP addresses, hostname/IP in an IANA-reserved range,
hostname is a not-yet-assigned by ICANN gTLD, dotless domains

Also minor refactor in PasswordProtectionService and
PasswordProtectionService to pass in web_contents in preparation for
showing interstitial.
