system_api: Add power_manager::kSetScreenBrightnessMethod.
Add a new "SetScreenBrightness" constant. The existing
powerd SetScreenBrightnessPercent is being updated to take a
protocol message instead of D-Bus args, so we might as well
rename it to be shorter at the same time.
BUG=chromium:881786
TEST=used with updated powerd
