Sync BundleHeader STL state with external expand/collapse

The state is now co-located with STL in @Composable. We had to pass
the ComposeScope because it has to be the remembered scope from the
@Composable otherwise there is a crash "A MonotonicFrameClock is not
available in this CoroutineContext"

I discussed this with Ale, as SceneContainer deals with this by using
a DataSource which is a heavy setup. We discussed several variants and
ended up with this one.

Bug: b/389839492 b/416516808
Test: Closed the shade while Bundle is expanded -> Bundle gets collapsed
  after opening the shade again the Bundle is in correct state.
