Separate hdcp levels into a base interface

Both media drm and HWC can share this common base code.
Run the following commands to freeze the aidl:
(1) m android.hardware.drm.common-update-api && m android.hardware.drm.common-freeze-api
(2) system/tools/aidl/build/hash_gen.sh hardware/interfaces/drm/aidl/aidl_api/android.hardware.drm/1 latest-version hardware/interfaces/drm/aidl/aidl_api/android.hardware.drm/1/.hash
