InputFlinger: Support amplitude control for InputDeviceVibrator
Add support for sending multi-channel rumble amplitudes to input
devices supporting FF_RUMBLE.
Bug: 38511270
Bug: 136215622
Test: Connect a gamepad whose driver supports FF_RUMBLE, find it
with the android input framework, and do something like this:
// waveform where rumble magnitude doubles every 2 seconds
VibrationEffect effect = VibrationEffect.createWaveform(
new long[] { 2000L, 2000L, 2000L, 2000L, 2000L },
new int[] { 16, 32, 64, 128, 255 },
-1);
inputDevice.getVibrator().vibrate(effect);
