Allows Launcher to recover gracefully into OverviewSplitSelect state
When Launcher restarts (as the result of a UiModeChange or something else), it attempts to recover its previous state. However, the OverviewSplitSelect state is unique because it requires some additional information to recover properly (the taskId of the staged task and so on). This change makes it so that the relevant information is passed forward in the recovery bundle. Launcher will now restart in the base Overview state, and then immediately apply the saved data to recover the OverviewSplitSelect state.
