[Qt-creator] External JSON library in Qt Creator

[Sze Howe Koh]

I just noticed that
https://github.com/qt-creator/qt-creator#json-library-by-niels-lohmann
still says, "Used by the Chrome Trace Format Visualizer plugin instead
of QJson because of QJson's current hard limit of 128 Mb object size
and trace files often being much larger."

Since https://bugreports.qt.io/browse/QTBUG-47629 was fixed in Qt
5.15, is it feasible and desirable to remove this dependency?
