    Deprecate savedInstanceState()
   
    We will now automatically save and restore the MutableState objects created via mutableStateOf() factory function with the known SnapshotMutationPolicy provided. For custom SnapshotMutationPolicy objects users will have to create a custom Saver objects.
   
    Relnote: Similarly to how we previously removed `state { 0 }` composable and now promote usage like `remember { mutableStateOf(0) }` we are going to remove `savedInstanceState { 0 }` composable. You should use `rememberSaveable { mutableStateOf(0) }` instead and it will save and restore automatically if the type used inside the MutableState can be stored in the Bundle. If previously you were passing a custom saver object now you need to use a new overload of rememberSaveable which has `stateSaver` parameter. The usage will look like this: `val holder = rememberSaveable(stateSaver = HolderSaver) { mutableStateOf(Holder(0)) }`
