Add interrupt command to acpiexec

Browse Source 
This commit add the Interrupt command to acpiexec.
The Interrupt command simulates an interrupt with a IntID (GSIV)
equal to the first argument of the call.

The acpiexec code simulates the behaviour by OSPM: execute the _EVT
method of the GED device associated with that IntID.
