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.
Fix: 345409060
Test: VtsHalVibratorTargetTest
Flag: EXEMPT HAL interface change
