qcacmn: Add new events to the interface manager

Add new events to the interfaces manager for the
following which requires inter vdev co-ordination
	1. ACS
	2. HT40 scan
These event are sent to the MBSS frameworkfor inter VDEV
co-ordination.

Add a string array ro represent interface manage events.
Add API to retrieve string from interface manager events.
