management: ensure Element::Error inherits from tlv::Error

Add static asserts to ensure ndn::nfd::*::Error are subclasses of tlv::Error.

Add WireEncodable and WireDecodable concept checks to
ndn::nfd::* classes that represent TLV abstraction.

Move definition of ChannelStatus, FibEntry, ForwarderStatus,
StrategyChoice methods into .cpp.

Move declaration of FaceScope, FacePersistency, LinkType
into encoding/nfd-constants.hpp.

Eliminate duplicate RibFlags declaration.
