Match Navigation Icon Colors Folded/unfolded

Recently we did color token migration for Taskbar which included navigation icon also, but phones and foldable device can't really adapt to new color tokens because of contrast issue with underlying wallpapers.

As a result, now home screen which default back to balck and white nav icon colors while all apps and in app navigation icon color will be themed to new GM3 Color tokens.
