4a/ Track visible running tasks via transitions observer
- When enable_shell_top_task_tracking is enabled, use the existing
task transition observer (until we have the generalized task repo)
to track the set of visible tasks for dispatching to Launcher.
In addition, update the paths to compose GroupedTaskInfos instead
of raw RunningTaskInfos so that we can later coalesce tasks that
should be bundled together for presentation in Launcher (or whose
joint states are required by launcher).
