Deprecate the DATA_SYNC FGS type.

The DATA_SYNC foreground service type will be deprecated starting from
Android version V. This does not affect any functionality and only logs
a warning message, giving developers a heads up that an exception will
be thrown if this type continues to be used in a future release.
