As a developer of Qt, I'd like to have more qdoc macros to help me with repetitive documentation tasks

Some examples (each macro should get a separate task in this epic, though):

• move/copy-assignment operators (QTBUG-129619, QTBUG-129772)
• move/copy constructors (dto, QTBUG-129619, QTBUG-129772)
• (member) swap (QTBUG-129573, QTBUG-129730, QTBUG-129772, QTBUG-129789, QTBUG-129790)
• destructors
• default constructor
• relational operators
• qHash() (QTBUG-129574)
• QDebug op<<
• QDataStream op<</op>>
• partially-formed (QTBUG-129619, also QTBUG-106251)
• mandates/contraints
• conditional noexcept
• ...
