Override lifecycle of always composed contents

This CL makes all STL contents (overlays, scenes) that are always
composed override their LocalLifecycleOwner so that:

1. It is max(CREATED, previousOwner.currentState) when the content is
   invisible.
2. It is max(RESUMED, previousOwner.currentState) when the content is
   visible.

This will make all lifecycle-aware utilities like
Flow.collectAsStateWithLifecycle() cancel their work when the content is
not visible. See go/flexi-alwaysCompose for details.
