    Qt: Defer proto tree column content resizing.
    
    Try to avoid the following call graph:
    
    ProtoTree::expandAll
      ...
        ProtoTree::expand
          ...
            QTreeView::resizeColumnToContents
    
    QTreeView::resizeColumnToContents calls sizeHintForColumn, which
    iterates over a number of items (default 1000). Calling it from
    ProtoTree::expand can lead to excessive wheel-spinning.
    
    Add a single-shot timer for resizeColumnToContents. This is similar to
    what QTreeView does internally when columns are resized.
