Rename Cp2PhoneLookup as Cp2LocalPhoneLookup and PhoneLookupInfo.cp2_info as PhoneLookupInfo.cp2_local_info.

To support remote CP2 contacts, there will be a new PhoneLookup ("Cp2RemotePhoneLookup") and a new field in proto PhoneLookupInfo ("cp2_remote_info").

In proto PhoneLookupInfo, cp2_local_info and cp2_remote_info will be of the same type ("Cp2Info").
