COIN should be able to run CI for repository using several versions of dependency

Marketplace add-ons can support several Qt releases. It should be possible to define several qt versions / modules from several qt versions as a dependency for any module in CI.

e.g it should be possible to define that new changes in https://codereview.qt-project.org/admin/repos/qt-extensions/qtquickcalendar are compiled against v5.15.1 and #dev (or a module sha from both branches)
