vibrator: Add a temperature awareness mechanism
From component reliability test results, the actuator
operating life is lower in low temperature.
Thus, we changed the voltage when device in a low
temperature to expand the actuator operating life.
Temperature rule:
> 10°C : Switch to "Normal Intensity" => Depends on each device's K file
5 ~ 10°C: This is a buffer period. Keep current voltage setting.
< 5°C: Switch to "Low Bound Intensity" => ~1.8 Vpeak(od_clamp=90), sine wave, F0-10.
Bug: 151063347
Test: remove vibrator properties and test VTS items
