Qt 6.4.0: 3rd party components: Check if updates are needed

There was related discussion in Qt Contributors Summit. Memo: https://wiki.qt.io/QtCS2018_Third-Party_Sources_Policy_and_Security

Following actions needs to be done for all Qt modules using 3rd party components

1. Check if we need to update some 3rd party components used
2. Check if documentation of 3rd party component usage is correct and do needed updates. Documentation here: http://doc.qt.io/qt-5/licenses-used-in-qt.html
   1. https://doc.qt.io/qt-6/licenses-used-in-qt.html
3. In case of 3rd party component update we need to document the update here: http://code.qt.io/cgit/qt/qtdoc.git/tree/doc/src/legal/licensechanges.qdoc
