nit: Can we instead exposing AppListController? In the future, we might want to
consolidate all app list methods to go through AppListController interface so
that we have less methods in Shell.

I actually tried this in an earlier attempt ;) The problem is that
ash::internal::AppListController isn't exported out with ASH_EXPORT, so there
are link errors trying to use that interface in chrome/browser.

So this might be better in a follow-up. I think we'd either need to move it out
of ash::internal and export it all, or export a new abstract interface that it
implements.

Exporting AppListController should be good enough as long as we only use it in
test or internally in ash. Think we already export some internal classes for
test.
