[gtk/wip/baedert/css-values: 70/102] Remove GtkCssRgbaValue

[Timm Bäder <baedert src gnome org>]

commit 67991ed0f405eca73e4c2f78f3e0d1c6c1a8de2c
Author: Timm Bäder <mail baedert org>
Date:   Fri Jan 10 13:02:33 2020 +0100

    Remove GtkCssRgbaValue
    
    The differenciation between a literal color value and an RGBA value
    caused problems in various situations. Just treat the two the same but
    don't allow access to the rgba value of a non-literal color value.
    
    This gets rid of around 1.6k rgba values in the widget-factory.
