[PATCH 9/11] ozone: evdev: Add a device event dispatcher that forwards to UI thread

ozone: evdev: Add a device event dispatcher that forwards to UI thread

This is part of a series moving IO on evdev devices to a fast thread,
since UI thread is too slow for the cursor.

Make a new class ForwardingDeviceEventDispatcher that wraps
EventFactoryOzone and can be safely passed to another thread. When the
other thread dispatches, we'll post to EventFactoryOzone on the UI thread
with the event.

I think it other way around works slightly better in this case:
ProxyDeviceEventDispatcher.

The long winded description is "DeviceEventDispatcherEvdev implementation that
proxies to EventFactoryEvdev".
