[Permissions] Use colorOnPrimaryContainer for the icon color

Currently, the background of the icon is colorPrimaryContainer and the color of the icon itself is colorPrimary. GM3 color token doesn't ensure contrast between colorPrimary and colorPrimaryContainer. As such, this CL uses colorOnPrimaryContainer for the icon color.
