    libide/code: add IdeSymbolNode:display-name
    
    This way we can separate items that have names and their display format
    (which is pango markup). The only thing using that was the xml symbol
    node, which we can quick fixup.
    
    This fixes showing things like impl<foo> in the symbol tree from languages
    that, you know, aren't xml.
