[TRACKER] Qt6 transition

[thunder-coding]

How the transition should be done

Note: this section should be considered incomplete. I'll appreciate some changes suggested by people who have maintained Qt family in the past.

• [x] Add Qt6 family of packages
• [x] Initial migration of a few packages to link against Qt6
• [x] Manual testing of the packages now linked against Qt6

  • 19464

• [ ] Complete transition to Qt6 for all packages that successfully link against it.
• [ ] Deprecate Qt5 family of packages, and finally remove it later

Just some remarks.

Qt 5.15.x is planned to reach EOL at 26th May 2023.

Qt 4.8.x reached EOL around 19th December 2015. On Gentoo (a GNU/Linux distribution), the last removal of Qt 4 components was taken took place on 7th August 2018, more than 2 years and a half after EOL. Obviously it is not at all easy to fulfill all the tasks.

Probably this issue should be updated. There are a lot qt6 packages and their dependencies now.

Yep I hadn't kept up with that. And with #21646 it's about to be a whole lot more.

[twaik]

octave package has an option of QT6 GUI, but it is not enabled. I tried to enable it, but it fails to be build (a lot of compiler errors).
