D5408: progress: [RFC] avoid ui.configbool() lookup when progress bar is active

[yuja (Yuya Nishihara)]

  The idea sounds good to me. Going further, maybe we can get rid of the `ui`
  reference from the progbar. There's a reference cycle.

  Probably missing `# developer config: progress.debug`. The checker isn't
  aware of `self` being `ui`.
