Build widevide modules with BOARD_VNDK_VERSION

Header libs are added since global include path is not provided when
building with BOARD_VNDK_VERSION. Also, some static libs are marked as
proprietary so that they can be linked against to the drm hal
service.

Bug: 33241851
Test: BOARD_VNDK_VERSION=current m -j
android.hardware.drm@1.0-service.widevine
