Dispatch keys to a device specific key handler

Injects a device key handler into the input path to handle additional
keys (as found on some docks with a hardware keyboard).

Configurable via overlay settings config_deviceKeyHandlerLib and
config_deviceKeyHandlerClass.

Change-Id: I6678c89c7530fdb1d4d516ba4f1d2c9e30ce79a4

DeviceKeyHandle: The device should consume only known keys

When the device receive the key, only should consume it if the device
know about the key. Otherwise, the key must be handle by the active app.
Also make mDeviceKeyHandler private (is not useful outside this class)
