Add InactiveUnused to Usage Report status

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/22963

This change kInactive to kInactiveUsed and adds kInactiveUnused to the
possible values for the status field in the Usage Report.  This CL
updates the header, the unit tests, and haystack and reference code.
