nfc: Add D-Bus client for NFC Record interface.

Implemented a D-Bus client for the org.neard.Record interface.
This CL also improves the way the object proxies are managed, so that
objects' life-time is managed correctly and the Added/Removed notifications
are properly sent to observers while supporting multiple adapters, tags, and
devices.

BUG=304979
TEST=1. chromeos_unittests
     2. Tested on an SCL3711 USB NFC adapter that records properties
        update properly, by looking at /var/log/chrome/chrome while
        running Chrome with --vmodule=*nfc*.
