Changed PhoneLookup#lookup to accept a DialerPhoneNumber.

There's a problem with the existing implementation of RealtimeRowProcessor; when CP2 information is not present, data from other sources can potentially be erased.

This CL fixes the problem by fetching the latest data from all sources, instead of just CP2. This requires being able to fetch PhoneLookup info without a Call, using only a number, so I changed PhoneLookup#lookup to accept a DialerPhoneNumber rather than a Call.

(The reason that it accepted a Call was to support CNAP so we'll need a revised solution for that later.)

There is a potential concern with performance in RealtimeRowProcessor due to performing a full [Composite]PhoneLookup vs. a CP2 lookup, because the full lookup includes network requests. However, it's anticipated that the real time lookups will very rarely have changes to apply so this might be OK as-is. If not, a mitigation strategy could be improving the performance of CompositePhoneLookup#lookup by short-circutiing slower sources when faster, higher priority sources have already completed.

A follow-up CL will write the result of RealtimeRowProcessor queries to PhoneLookupHistory to further reduce how frequently real time updates need to be applied.
