    keyboard: Add generic handling for key actions
    
    These actions are defined in the JSON files themselves, allowing
    us to migrate away from the sets of pre/post default keys, and fold
    them into the JSON files for fuller control on layout and appearance.
    
    As a first migration step, handle the relevant actions in the buttons
    created from the JSON files, so we can port these.
