plugin: register plugins for the plugin-specific usages

Browse source 
The debounce, wheel/wheel-low-res, double-tool and eraser-button plugins can limit
themselves to a specific usage.

The mtdev plugin needs to pass each each event to mtdev and the proximity
timer plugin needs to get each event's timestamp so they cannot be
restricted.

The forced-tool could be restricted but effectively any event on the
devices it works on will have one of those usages set so there's no
point.
