drm/amd/display: add visual confirm colors to differentiate layer_index > 0

[WHY]
Currently there is no way to visually identify if there is one or more
layers presented fullscreen on the display

[HOW]
Add new visual confirm colors in get_surface_visual_confirm_color for
planes with layer_index > 0
