[gtk/wip/baedert/css-values: 1/3] Remove GtkCssRgbaValue

commit dfe19b8ca11302c1e4a7ecaed23f2fe5e117b3b5
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.
