[gtk+/wip/css: 96/125] css: Redo value resolving



commit 5a0b23a09f5056c365a1e7b71dac3b53980a8879
Author: Benjamin Otte <otte redhat com>

    css: Redo value resolving
    
    Instead of on-demand resolvage, we now resolve during lookup. The step
    is done via
      _gtk_css_style_property_compute_value()
    which currently calls into
      _gtk_css_style_compute_value()
    That function has all the old resolving machinery.
    
    The only part missing for now is the handling of win32 code. It will be
    added back later.
