exo: gamepad: Send device version to ARC

This is a follow-up change of https://crrev.com/c/1602193 and
https://crrev.com/c/1599758.

After the first change landed, gamepad vendor ID and product ID are
exposed to ARC. However, device version wasn't included because the
field wasn't available in ui::InputDevice. After the second change, now
the information is available.

This is a part of the effort to improve ARC Gampad compatibility.
