Do not show pointer for disabled device

We currently display the pointer for all devices that support displaying
it, but there are actually some devices that are disabled and shouldn't
actually have it displayed for them, here's an implementation for that.

This is done by adding an enabled state to the InputDeviceInfo to
determine its disabled status.
