Lioncash e05d2a70b2 common/input: Avoid numerous large copies of CallbackStatus
CallbackStatus instances aren't the cheapest things to copy around
(relative to everything else), given that they're currently 520 bytes in
size and are currently copied numerous times when callbacks are invoked.

Instead, we can pass the status by const reference to avoid all the
copying.
