Decrease the inferred auto-brightness adjustment at the extremes.
Now that the brightness slider always represents the brightness of the
panel, rather than the auto-brightness adjustments like it did prior to
P, we need to infer the adjustment by comparing the old and new
brightness values. At the extremes, this inferred brightness increases
dramatically towards (+/-) infinity, so we use a different strategy.
Based on dogfood feedback, the current inference seems to have too
strong of an effect, so we're cutting it in half in the hopes that this
is more reasonable.

Added gamma correction to autobrightness.
Moved the gamma correction determined by the brightness adjustment to the brightness mapping
strategy, and added a best-effort attempt to gamma correct the curve to meet user data points
before resorting to spline-bending.

Added safeguards for pushed brighntess curve.
Currently, the only safeguard is making sure the brightness curve isn't too dark to turn
auto-brightness off (or connect the phone to a computer and reset the curve with ADB).

Reset brightness adjustment when user sets brightness directly.
If the user has a non-zero brightness adjustment then short-term model
returns an incorrect value after they make a direct change to the
brightness with auto-brightness on, which then looks like the
auto-brightness is ignoring their input. To avoid this , if they're
making a direct change to auto-brightness go ahead and reset the
brightness adjustment.

Slider always represents absolute brightness
Currently the slider represents a gamma adjustment to the brightness
curve when auto brightness is enabled and the absolute screen brightness
when it's not. This is a fairly confusing behavior to most people, so
this consolidates them to a single behavior: the slider always
represents the current brightness and auto-brightness will automatically
adjust it.
This also moves a bunch of the brightness methods from PowerManager over
to DisplayManager, since it's really the DisplayPowerController that's
responsible for determining and setting the display brightness.

Track brightness changes in nits rather than backlight values.
For the moment, the only one that actually knows the true brightness
value is the DisplayPowerController, so have that tell the
BrightnessTracker directly when brightness changes.

Add an API for setting a new brightness curve.
In addition, this also provides multiple strategies for mapping from
ambient room brightness in lux to display brightness. The default one is
the classic strategy, where we map directly from lux to backlight
brightness in an arbitrary unit. The newer and preferred strategy is to
use the physical brightness of the display, but requires that the
brightness properties of the display are appropriately configured.
