Add a new KEYBOARD_TAP haptic feedback type for very short, low-latency vibration.
The minimum value varies from device to device, so this is useful for defining
the shortest and most efficient vibration. The VibratorService creates a Thread
when playing back vibration patterns, so this allows you to avoid thread creation
and associated scheduling delays by specifying a one-shot duration in the config
file.
