API: icontheme: Add 2 new GtkIconLookupFlags

Browse Source 
GTK_ICON_LOOKUP_FORCE_REGULAR and GTK_ICON_LOOKUP_FORCE_SYMBOLIC can be
used to force a regular or symbolic icon to be loaded, even if the icon
names specify a different version.

This is intended to support the CSS property -gtk-icon-style.
