st-widget: Add automagic rtl/ltr pseudo classes
At times, RTL locales require different CSS, so always create theme nodes with :ltr/:rtl pseudo classes depending on the widget's text direction, to provide an easy way to handle those cases without requiring a separate stylesheet. https://bugzilla.gnome.org/show_bug.cgi?id=643835
