power: Add activity watcher for body detection

Add the activity sensor detection in UserProximityWatcher.
If there is an available activity sensor, start to listen on it just
like SAR sensor.

Also add following prefs entries for handling activity proximity event:
kSetCellularTransmitPowerForActivityProximityPref
kSetWifiTransmitPowerForActivityProximityPref

Add unittest for testing detection of activity sensor.

BUG=b:123434029
TEST=FEATURES="test" emerge-trogdor power_manager
TEST=On lazor, while the activtity sensor presents, watch the powerd log.
     If the set_wifi_transmit_power_for_activity_proximity is set,
     log shows "[INFO:user_proximity_handler.cc(53)] New proximity sensor with id 17:  wifi".
