Add feature to disable building tests

IFW requires static build of Qt which does not build tests on all
configurations. This allows building modules without them building tests. Previously IFW used 5.15 repos, those build tests in test workitem, not running into the issue.

This is only relevant if the tested repo i.e IFW implements it's own
test instructions.
