Introduce Device Controller to InputReader
Introduce Device Controller to manage non-evdev devices associated with
the input device kernel interface. These devices doesn't interact with
inputflinger with input events which requires a mapper to process the
raw event with assoicated input sources.
Bug: 180342233
Test: atest inputflinger_tests
