Migrate to NfcStatsLog from StatsLog

As part of statsd becoming a Mainline module in R, autogenerated
StatsLog.write() calls are going away and being replaced by *StatsLog.java
that is autogenerated for each module.
This CL adds autogenerated NfcStatsLog and replaces usages
of StatsLog with NfcStatsLog.
