lunaa: WIP: Redo brightness configuration and move partially to displ…

…ayconfig

* Updated minimum brightness calculation from 4/2047 to 4/2784
to align with display DTSI's max level (qcom,mdss-brightness-min-level = 1,
qcom,mdss-brightness-max-level = 2784).

* Synced screenBrightnessRamp with Oplus SM8650.
screenBrightnessMap is preferred as it supports only floating-point values.

* Calculated High Brightness Mode (HBM) transition point as 2047/(2784-4)

* Removed some overlays so as to prefer the defaults.

* Update auto brightness overlays from stock display dumpsys under
OplusSmartBrightnessController.
