Move MinimizableInfoBars from CppEditorDocument to IDocument

Similar to the InfoBar.

The only thing that an editor implementation needs to do is to set a
settings group and the possible info bars in the document constructor.
And later call document->minimizableInfoBars()->setInfoVisible(id,
visible) to manage the state.
