Add binder_service_stable_android
Add a new binder service that uses the exact same service delegate as
its implementation, but exposes itself with the IUpdateEngineStable* APIs.
Note: Even though the new interface requires only one binding at a time,
race conditions for different clients are NOT handled in this CL.
Multiple binding is still possible via the unstable IUpdateEngine API
and via the Java android.os.UpdateEngine interface. Moreover, bindings
with bind(IUpdateEngineStableCallback) and bind(IUpdateEngineCallback)
are handled separately.
Test: unit test
