Introduce vibrator frequency mapping.

Introduce frequency data to VibratorInfo and a transformation for
VibrationEffect that maps relative frequency and amplitude values to the
device absolute values.

The transformation also clips amplitude values to the device bandwidth
map provided.

Pending implementation of chaining composed waveforms and sending PWLE
primitives to the HAL.
