Device: Implement Ethernet PHY MDIO Communication

The following fixups were added during the squash/merge:

Fix formatting in EthPhyMessage and EthPhyRegPacket
Device: Use std::make_shared when creating the EthPHYControl filter
Network: Create NetID String for EthPHYControl
EthPhyRegPacket: Constants in PascalCase
