Fix broken vibration vendor effect tests in staging

Some fixes to new VibratorEffect.VendorEffect APIs:

- Add helper method to perform deep comparison of PersistableBundle
  instances. The BaseBundle.kindOfEquals doesn't work well on array
  values.
- Make sure VibrationEffect.createVendorEffect triggers the validate()
  method before returning the new instance.
- Fix service tests to grant new permission before testing vendor
  vibrations.
