Remove kSystemMenuIconColor and kSystemMenuIconColorToggled. Feature pod
button use kButtonIconColor and kButtonIconColorPrimary in the spec.

Make FeaturePodIconButton as ImageButton only. Since it already has
|toggled_| to control the toggle state. Update the icon color on
|toggled_| is enough for it.
