Support mouse pointer on external displays (1/2)
If input source is mouse, InputTouchMapper and CursorInputMapper will assign
a PointerController which associated with some display.
When dispatch a motion event, it should be assigned the displayId from
PointerController.
- Add getDisplayId for PointerControllerInterface to get the current
associated display id.
- Add updatePointerDisplay for InputReaderPolicyInterface to find and
associate the specified display viewport.
- Add test cases for TouchInputMapper and CursorInputMapper.
