Add unit test for preloaded license

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/96508

This adds a unit test for to verify that a preloaded license may be
loaded into OEMCrypto. A preloaded license is a license that does not
have a nonce, and for which there is no license request. This is used
in CAS and ATSC.

I also updated the test version string to
OEMCrypto unit tests for API 16.2. Tests last updated 2020-03-27

Bug: 144105097
Test: ran oemcrypto unit tests on taimen and with v16 modmock.
