This allows the OEMCrypto session state to be accessed by tests in other modules. For example, keys can be added for testing encryption and decryption operations in CDM-level tests. Merge from Widevine repo of http://go/wvgerrit/18127, http://go/wvgerrit/18591, http://go/wvgerrit/18581 and http://go/wvgerrit/20802. Change-Id: Ie0d071a2da610c0856ae6356a0abf054013a1b87
