Merge from Widevine repo of http://go/wvgerrit/95403
This updates the test code CreateDefaultResponse to make sure that
license releases do not have a core message, and that the key control
block is correctly set for renewals.
Also, the unit test OEMCryptoUsageTableTest.TimingTest is changed to
only a license release when the license is inactive. If the license is
still active, then the license is loaded before generating a usage
report.
Test: Ran full unit tests
