Remove qt6_use_modules

qt5_use_modules has been deprecated in 2013 (commit d9ea4bb144153)
and removed for the first time in 2018, but then brought back - see
discussion in https://lists.qt-project.org/pipermail/development/2018-June/032837.html .

Anyhow, I think we can finally put it to a rest in Qt 6.
