Cong Lin 9935fae50d Loosen KCB encryption checks in L3
This is a merge from:
https://widevine-internal-review.googlesource.com/c/cdm/+/152372

The L3 source change which produced these libraries is:
https://widevine-internal-review.googlesource.com/c/cdm/+/152371/

Original commit message:
To address the bug with certain 16.4.x SDK versions returning a
clear key control block (KCB) for clients newer than 16.5, the
exact version check to determine whether key control blocks are
clear or not has been loosened.

Original behavior:
- ODK version >= 16.5.x --> Assume clear
- ODK version <= 16.4.x --> Assume encrypted
New behavior:
- No KCB IV --> Assume clear
- Otherwise --> Assume encrypted

This CL also includes a change to oemcrypto/include/OEMCryptoCENC.h
The changes to OEMCryptoCENC.h in the CL are comments or variable name
change. So it should be safe.
This change was merged to wv tm-dev here:
https://widevine-internal-review.googlesource.com/c/cdm/+/148411
So, adding it to Android tm-dev.

Test: run_level3_static_tests, CdmDecryptTest/CdmTestWithDecryptParam.* against LS SDK 16.4.2 & 17.0

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
