Part of Qualcomm L1 OEMCrypto integration on mako

bug: 8621521

This fixes a problem where insecure audio buffers were being
passed incorrectly as secure buffers to the trusted
environment's OEMCrypto_DecryptCTR.

This is a merge of the following changes from the widevine
git repository to android git repository:

https://widevine-internal-review.googlesource.com/#/c/5163/2
Allow selection of secure/non-secure buffers

https://widevine-internal-review.googlesource.com/#/c/5164/
Pass Secure Buffer Request to CDM
