Remove simplifyQtSignalsSlots(), update qt.cfg

We don't seem to have a way to load a library in a test and also apply the defines from it, so I just removed the tests.
Nevertheless, I think qt.cfg does everything the simplification code did.

[firewave]

That would be something to looking into. I do not know what does apply the defines. I would prefer to keep the tests.

You could also write a system/Python test instead.

You would have to use Preprocessor somehow, but I couldn't figure it out. It's not done in any other test either.
The tests basically check that we can replace a define with nothing, so meh.

[firewave]

The usage of Preprocessor in the tests is probably flawed and possibly needs to be reworked. That's actually not something I want to look into as well as currently nothing can even be remotely finished up for a boatload of reason...

It does a bit more and it appears it just replaces things in certain places.

Those checkLibraryNoReturn warnings are annoying for signals, which may not have a visible implementation. We should probably only warn if the function is completely unknown.
See https://trac.cppcheck.net/ticket/11190 and https://trac.cppcheck.net/ticket/11523

cfg tests also work 👍

And I asked for the tests to be kept since there was much more logic in that removed function which appeared to be missing elsewhere. No idea why I didn't express that.

Please remove the checkLibraryNoReturn suppressions or mark it as a draft for now as the CI will fail when this and #4809 have landed.

I don't have an idea about that. But removing simplifyQt and using qt.cfg that sounds very good to me 👍
