Add a listener when task snapshots change
Since we start recents before we take the snapshot, we need to add
a mechanism to inform recents about task snapshots changes.
We add a new method to TaskStackChangedListener,
onTaskSnapshotChanged, which gets called whenever a task snapshot
changes. Then, SystemUI registers such a listener and updates the
task thumbnail view for the specific task.
Test: Open app, press recents, make sure thumbnail is up-to-date
