Remove experimental twilight-based automatic brightness
Bug: 31602449
Test: verified adaptive brightness no longer varies with twilight with
"brightness_use_twilight" set to "1".

TwilightService v2.0
- Switched to using CalendarAstronomer for more accurate sunrise/sunset
times.
- Exposed sunrise/sunset times via TwilightState so that clients can
track the current twilight period and perform their own
interpolations.
- Adopted LocationRequest API for fused location updates:
(low power, min 1h, max 10m).
- TwilightService is now only activated when a listener is registered,
minimizing impact to system health on platforms / configurations
where twilight state is not needed.

Add ambient light ring buffer for initial data gathering period.
We're seeing reports of the display being too dim at initial wake up.
Saving the buffer for this initial period lets determine whether this
is a calculation error or something wrong with the sensor readings.

SysUI Tuner: Night mode v3
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.

Customize auto-brightness parameters
Auto-brightness parameters are device dependent so they should be
configurable.
The common issue with original values manifests as the screen being
perceived as too bright in dark rooms with minimum brightness and
also laginess on backlight change.

Add code to collect data about auto-brightness adjustments.
Write samples of the old and new state to the binary event log whenever
the user modifies the auto-brightness adjustment. We wait a few seconds
before logging to ensure that the user is satisfied with the adjustment.

Allow dreams to control screen state and brightness.
Added setDozeScreenState() and setDozeScreenBrightness() methods to
DreamService. The values specified here only take effect once
startDozing is called and can be changed while dozing.
This required some significant rework of the display power controller
but the result seems quite nice and better represents the policy
we want to apply.
Changed the test dream a little bit to make it flash the screen
every minute using the new functions.

Move display power controller to display manager service.
This refactoring is in preparation for enabling the display manager
to have more control over the blanking state of individual displays.
There are no functional changes. Some bits will be cleaned up in
a subsequent patch.
