[VrShell] Centralize color handling and enable close button on fullscreen

This updates all of the existing hard coded colors to use colors from the scheme instead of hardcoding (so they can change with the mode).

The naming of colors in the scheme was also updated for better
consistency and to differentiate from world environment colors.
