Introduce IVibrator.performVendorEffect

Introduce HAL API to perform vibration effects defined by the vendor.

The new API accepts a PersistableBundle representing the effect and some
platform-provided parameters, e.g. EffectStrength and scale.

The callback support for completion is required for this API, since
effect duration is undefined.
