Description: Make it possible to determine if a composable was initialized or recomposed or it has been cleared without having to use viewModel.

Use Case: I want to use a different architecture than a viewModel for my compose app. When my compose view appears I would like to trigger a function that will make a network call. I could do it with a LaunchedEffect but it would retrigger on orientation change or when navigating back to the screen. I want to avoid this and have a function that wouldn't always retrigger. I was thinking of a function named LauncedSaveableEffect that would have similar behavior to the rememberSavable used together with LauncedEffect, like this:

var init by rememberSaveable { mutableStateOf(false) }
if (!init) {
    LaunchedEffect(Unit) {
        // make the call that triggers the network call
        init = true
    }

Also, it would be nice to have info about when to view is not displayed anymore similar to the onCleared function of the viewModel so that I can clean up once my view is not visible anymore. I was thinking for this a method DisposableSaveableEffect could work the best, I imagine it could look like this:

DisposableSaveableEffect(Unit) {
    // make the call that triggers the network call
    onDispose {
        // cleanup because my view is not visible anymore
    }
}

Currently, this second option is not even possible to be mimicked not even with the rememberSaveable. This makes it really hard to work with compose if you are using any other architecture other than viewmodel.
