[enocean] Added tariff info for AutomatedMeterSensor ThingType channels (#9333) (#9361)

* Added new channel parameter tariff to channels instantpower, totalusage, currentFlow, cumulativeValue, counter and currentNumber
 * Parameter is currently just read by EEP A5_12, which is used by AutomatedMeterSensor ThingType
 * AutomatedMeterSensor ThingType has extensible channels now

Fixes #9333
