Input: Make CheckPassiveGrabsOnWindow take InternalEvent

Browse Source 
Previously, it only took DeviceEvents, but it would be much more useful
if it took InternalEvents.  Any event that activates a grab must still
be a DeviceEvent, so put in a check to enforce this.

Change all callers to make the appropriate casts.
