Subject: [PATCH] Update brightness curves for taimen

Update brightness curves using curves from
https://cs.corp.google.com/piper///depot/google3/java/com/google/android/libraries/smartbattery/brightness/model/DeviceCurves.java
Sampled at integer log values from 0 to 5000.

Bug: 74386763
Test: Manual, flash device, adb shell dumpsys display and check brightness config.
Test: try phone near window and in dark area check brightness is reasonable.
Test: Push zebedee curve, check curve is the same as built in version.
