[librsvg: 2/13] Store the stylesheets in the Document

[Federico Mena Quintero <federico src gnome org>]

commit 9e4be3342094025df2eef9ad752c0557136c1f93
Author: Federico Mena Quintero <federico gnome org>
Date:   Thu Jan 16 19:16:10 2020 -0600

    Store the stylesheets in the Document
    
    Instead of discarding them after DocumentBuilder performs the initial
    cascade.
    
    We'll use the saved stylesheets to re-cascade if needed.
