TwilightService:
- Add support for locking on/off twilight globally
- Change twilight state to have float amount rather than
having clients calculate it using the sunrise/set values
- State controlled through secure setting
- Override mode which locks to a state for a couple hours then
resets
- Add broadcast for SysUI to listen to
Brightness/Power:
- Updates to handle TwilightService changes
- Added secure setting to control whether or not to use
twilight when calculating brightness.
Tuner:
- UI Overhall
- NightModeController will set the values of the custom color matrix
taking into account the current twilight service state and any
custom calibration set by the user.
- Probably other stuff.
