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.
