Add Integration Tests for App Jank Tracking

This change adds tests to verify the following:
  * Platform widgets can obtain a JankTracker object.
  * Platform widgets can report state changes that are tracked.
  * Call reportAppJankStats from a view and see an increase in
    pending stats count.
  * When activity is no longer visible jank tracking is paused.
  * When activity is resumed jank tracking is re-enabled.
