Check L3 for secure stops

Browse Source 
[ Merge of http://go/wvgerrit/151512 ]

Parameterizing GtsMediaDrm tests exposed a few issues. If secure stops
were stored at L3 security level, retrieval would fail. This CL
checks L3 if the secure stop was not found at the default security
level.

Bug: 221249079
Test: GtsMediaTestCases
