Improve query performance

Browse Source 
[ Merge of http://go/wvgerrit/15780 ]

Android mediaDrm allows callers to serially query status information through a
property API. CDM however retrieves all status information in a map and
filters out all but the relevent one. This leads to delays in Netflix app
startup. Rewriting the CDM interface to return only the queried value.
