[librsvg: 1/7] Add a NodeData::get_chars() function

[Federico Mena Quintero <federico src gnome org>]

commit 7d1e3837ea9f6ef58549a6de5baa0e8736d196e2

    Add a NodeData::get_chars() function
    
    We'll be changing the internal representation of the "chars" node
    vs. other real SVG element types.  So, instead of the usual
    .get_impl::<NodeChars>() we'll have this explicit function.
