D29826: [KMainWindow] Invoke QIcon::setFallbackThemeName (later)

[Igor Poboiko]

  My main motivation here is following: https://gerrit.libreoffice.org/c/core/+/94691. 
  If it gets accepted, it would fix long-standing issue that people aren't able to use Libreoffice with KF5 integration plugin together with dark color scheme (and "breeze-dark" icon theme) out-of-the-box.

  In short, people suggest using gtk3 VCL plugin, because it hooks with kde-gtk-config which exports KDE icon theme to GTK. Instead of native KF5 VCL plugin. What a shame!
