Consider updating the BatteryImageInfo struct to no longer need the IconBadge enum. See the TODO in ash/common/system/chromeos/power/power_status.h: "Consider using gfx::VectorIconId instead of this enum once all possible badges have been vectorized". Note that this TODO is slightly out of date as worded since we no longer use gfx::VectorIconId; the VectorIcon struct has since taken its place.
