[WPP2] Hide preview bottom components when overlay tabs are shown

For deciding show/hide of the bottom components, we need to take care of 2 cases
1. When on color update, we need to set the QSB flag and re-render the
   surface
2. When show/hide the wallpaper control, we specifically send a message
   to show/hide the workspace bottom components
