Generalize network_event_log -> device_event_log

This CL:
* Moves network_event_log.cc -> device_event_log_impl.cc
* Defines macros and initialization code in device_event_log.h
* Modifies network_event_log.h to use device_event_log instead.
* Converts PowerManagerClient logging to use POWER_LOG as an immediately useful example.
* Adds the non-network log entries to a 'device_log' entry in chrome://system and feedback reports.
