Use ISF-defined values when processing input device events

Use ISF-defined values when processing input device events

Since the ECORE_EVENT_* values are not constants, they can't be
guaranteed to be the same over processes. For this reason, the
existing method to send ECORE_EVENT_* value directly to a different
process causes malfunction.
Thus, we define input device type enum at ISF side to ensure
the values at sender side and receiver side is consistent.
