Add bright background color

This adds a bright background color. It is currently unclear to me how
this would be used and it is likely that it is not possible to use the
bright background color at the moment.

The bright background color behaves the same way as the bright
foreground color and falls back to the background color when not set or
`draw_bold_text_with_bright_colors` is `false`.
