ACPICA: Add interrupt command to acpiexec

ACPICA commit ef7cf185a046d76119b631f16e7c991543c80edc

This commit add the Interrupt command to acpiexec.

The Interrupt command simulates an interrupt with a int_ID (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 int_ID.
