By adding these stubs, they will be automatically added to framework.aidl
in sdk builds.
This makes it easier for unbundled apps to pass these objects across
AIDL calls.
ContentValues & CursorWindow are already public Parcelables. It is an
oversight that they were not already in framework.aidl.
There are a lot of other public Parcelables that are missing from
framework.aidl. This just fixes two commonly requested ones.
