[gnome-builder] lsp: add override for style-scheme kind

    lsp: add override for style-scheme kind
    
    This allows a plugin to specify what IdeSymbolKind should map
    to. I'll note that we could drastically shrink the memory
    overhead here by reversing the style type, but I'll leave that
    to a future commit.
