CI: turn on assertion checks

[Chocobo1]

This turn on assertions from qbt codebase so that testers can verify the assertions really hold.

Are they turned off? Or do we produce release builds on CI for some reason?

Are they turned off?

Yes, due to QT_NO_DEBUG defined via Qt library.
Qt cmake script will define it by default for every mode except debug mode. Even none/empty mode has it defined.

Or do we produce release builds on CI for some reason?

I would like the CI artifacts to still be fast enough. Full debug mode might be too inefficient.

Strange... If I'm not mistaken, we've seen assertions triggered even in official builds.

I don't know, maybe the official builds used different set of compile flags.
