Changes in ImeTracker to be compatible with the InsetsController refactoring

- passing the statsToken (via `InsetsController#reportRequestedVisibleTypes`), and `onControlsChanged`
- setting the mStatsToken in the ImeInsetsSourceProvider after the IME was started/hidden to use when the IME control is dispatched
- adding new phases
