[WIP] Trial move on making it compiled with kf6 libs

[Brli]

I tried a bit and copy/paste from multiple kde source to merge away from krun.

it currently has major unfunctional part:

the file chooser dialog pops only once, rather it's a upload or a download request, and never pops again, even triggering the same request, ie. click to save the same pic or click the same "click to upload" element.

the system:

OS: Arch
Firefox: 123.0.1
GUI Session: Plasma6 Wayland
Firefox: wayland

the best approach would be to pass things to xdg-portal and let it handle all these requests.

Yes, that's also my plan

firefox keeps reporting this to terminal, don't know if relevant.

strace suggests that (yes, trying a nightly build from mozilla-central mercurial source with kde patches and co.)

it seems somehow Helper::handleGetOpenOrSaveX() is written purely in Qt, instead of Kf5 libs.
