[Development] Qt 6 co-installability with Qt 5

IMHO, suffixing our binaries is a kludge. It “solves” the major version transition, but not any of the other use cases such as minor version upgrades, different builds of the same Qt version, etc.

Qt Creator already provides a way to manage and switch Qt versions: https://doc.qt.io/qtcreator/creator-project-qmake.html

What we need is a command line tool for doing the same. That’s how other project solve things too (nvm, rvm, pyenv, etc). And we already have a tool for that, qtchooser. If maintenance of that is an issue, then let’s solve that.

Why is that not an acceptable solution for distros?

Have we fixed it?

I do not plan on updating qtchooser for Qt 6. Qt 6 should not install any
binary with the same name as Qt 5 did.
