Fix refresh rate callback fan-out for choreographer

* AChoreographer receives refresh rates from DisplayManager
already, so there's no need to default-enable them - AChoreographer only
needs to pump an event with the latest refresh rate to wake up looper. This
also ensures that AChoreographer's callbacks are entirely in-sync with
DisplayManager since there's no raciness.
* Instead of re-requesting a config change from SF, instead inject it in
AChoreographer correctly to save on binder.
