License release does not use core message

Merge from Widevine repo of http://go/wvgerrit/99843

When processing a license release, the license is not loaded, so
OEMCrypto does not know nonce version information for the core
message. It assumes that all license releases are v15, so it is not an
error for a license release to not have a core message.

This CL also adds some extra logging to tests so that we can track
content id and the pssh. This CL also updates some of the test content
policies when running the local license server. The local license
server is only used for debugging problems.
