Add an adapter to bridge ECC data and emergency dialer UI

- EccInfoHelper is not instanciated in EmergencyDialer yet, it's
waiting for a proper IsoToEccRepository to supply EccInfo.
- After get current country's EccInfo list from EccInfoHelper, apply
the EccInfo list to EccShortcutAdapter.
- With EccShortcutAdapter, each EccInfo will show as a shortcut button
in EmergencyDialer. The types of an EccInfo will be combined together
to generate the description string for the shortcut button.
- Add strings for ECC types.
- Add police and fire icon resources.
