Description
Each individual class that supports the spaceship operator in C++20 builds should already mention this in the docs (needs confirmation).
The reverse is not true: we don't have a list of Qt types that support the spaceship operator. Esp. in Qt 6.8 and 6.9, where not all classes have been ported, yet, such a list would be good starting point for users that wish to learn about C+20 support, and could be linked from the C+20 overview page, too (cf. QTBUG-128837).
Acceptance criteria:
- add a new \group, say three_way_comparables
- add each \class that has a spaceship operator in C++20 builds to that group
- display the group in a suitable location
- link that location from the C++20 overview page (cf.
QTBUG-128837)
- link that location from the C++20 overview page (cf.
The "suitable location" is probably not the C++20 overview page itself, because that list will become long, so it should probably be a separate page, akin to https://doc.qt.io/qt-6/datastreamformat.html
