face: LpFace counters

FaceCounters for LpFace consist of LinkService::Counters and
Transport::Counters. Old FaceCounters class from 2014 face architecture is
renamed as OldFaceCounters, and can be wrapped with new FaceCounters class.
OldFaceCounters is only used in old Face subclasses.

This commit also updates existing face test suites to use new FaceCounters,
updates ForwarderStatus so that it does not rely on FaceCounters,
and moves the logic of copying face properties and counters into management
structs from face system into FaceManager.
