nfc: Add D-Bus client for NFC adapter.

Added D-Bus client code for the NFC Adapter interface.

BUG=304979
TEST=1. chromeos_unittests
     2. On Chrome OS machine, adding and removing a USB NFC adapter should
        cause adapter object proxies to get added and removed. Tapping an NFC
        tag or a Nexus 4 device should log property change events.
