Have a new API to get private DNS mode

Browse Source 
- Expose PRIVATE_DNS_MODE_OFF, PRIVATE_DNS_MODE_OPPORTUNISTIC and
PRIVATE_DNS_MODE_PROVIDER_HOSTNAME for external users.
- Since PRIVATE_DNS_DEFAULT_MODE_FALLBACK might be changed from
release to release, so it cannot be exposed as a system API.
Remove PRIVATE_DNS_DEFAULT_MODE_FALLBACK and have a new API -
getPrivateDnsMode() for users to get the private DNS mode instead.
