Update ODK Library and add license release unit test

Merge from Widevine repo of two CLs.

Merge from Widevine repo of http://go/wvgerrit/94743

A license release should not have a core message. This CL adjusts the
existing unit tests to verify this. There is also a new unit test called
SecureStop that explicitly tests sending a secure stop in a new
session without first loading the license.
