Key Status should reflect key container security level

[ Merge of http://go/wvgerrit/77506 ]

Callers of MediaDrm can register to be notified when key status
changes and if they are usable for decryption. A number of factors
are evaluated when making this determination. Key container security
level will now be included in the evaluation.

Bug: 78652608
Test: WV unit/integration test, GtsMediaDrmTest, Play movies playback
      testing.
