Theme dark version of brand color and guided actions background

Follow the same strategy for defaultBrandColor/colorPrimary,  introduce
defaultBrandColorDark/colorPrimaryDark for details action background.
Remove the code that auto-calculate dark version from defaultBrandColor.
Simplify HeadersFragment and FullWidthdetailsOverviewRowPresenter code
by using theme attribute in layout file.

Follow the same naming convension, renamed guidedButtonActionsBackground
to guidedActionsBackgroundDark for the "dark" version.
