Cong Lin f10acda463 [RESTRICT AUTOMERGE] L3 Load RSA key from two parts and re-generate 
build

This is a merge of CL from widevine repo (obfuscated code only):
https://widevine-internal-review.googlesource.com/c/cdm/+/124885

The source code change that produced the obfucated code is also included
in the CL above but will not be merged to Android.

Original commit message from the fix above:
"This is a security improvement against an L3 exploit b/182584472.
The change is to store RSA private key in two parts instead of one,
and load it separately when the key is needed. This will make it
more difficult to find the entire RSA key.

This CL does the key loading part only. Key splitting is done
in Haystack in CL: cl/367515385"

New L3 system IDs included in the obfuscated code:
ID     Description
22585  Android Q ARM L3 Field Provisioning 3.0
22586  Android Q ARM 64 L3 Field Provisioning 3.0
22587  Android Q x86 L3 Field Provisioning 3.0
22588  Android Q x86 64 L3 Field Provisioning 3.0

Bug: 182584472
Test: L3 unit tests
Test: GTS tests

README 

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:
