Reapply "Fix DreamOverlayService memory leaks."

This changelist re-introduces fixes to address memory leaks in
DreamOverlayService by making sure components are not reused between
dream instances to prevent torn down components from being used again.
To address this, the components are recreated from the passed in
factories.
