Component used: Activity

Version used: 1.7.0-alpha02

It would be really convenient if ComponentDialog, in addition to implementing LifecycleOwner and OnBackPressedDispatcherOwner, would also implement SavedStateRegistryOwner.

That SavedStateRegistryOwner should be plugged into the Dialog class' onSaveInstanceState and onRestoreInstanceState.

This would make it much easier to use Jetpack Compose in a ComponentDialog, since Jetpack Compose requires both a LifecycleOwner and a SavedStateRegistryOwner attached to the Window via the ViewTree APIs.
