Mac and Android still override HandleAccEvent for platform specific behaviour other than firing the event. The Android behaviour can be unified properly in future work. ATK is the platform layer with the most churn because there were inconsistencies in the way local and remote events were handled. I'm reasonably sure these were unintentional inconsistencies, so I've done my best to unify them. Differential Revision: https://phabricator.services.mozilla.com/D183704
