QDoc should ignore non-documented reimplemented static functions and static public members

QDoc 5.11 with Clang generates entries in the documentation for  reimplemented static functions and static public members even if they are not documented. For example:

• metaObject: http://doc-snapshots.qt.io/qt5-5.11/qwebenginedownloaditem.html#metaObject
• metacall: http://doc-snapshots.qt.io/qt5-5.11/qwebenginedownloaditem.html#qt_metacall
• metacast: http://doc-snapshots.qt.io/qt5-5.11/qwebenginedownloaditem.html#qt_metacast
• tr: http://doc-snapshots.qt.io/qt5-5.11/qwebenginedownloaditem.html#tr
• trUtf8: http://doc-snapshots.qt.io/qt5-5.11/qwebenginedownloaditem.html#trUtf8
• QGadgetHelper: http://doc-snapshots.qt.io/qt5-5.11/qwebenginefullscreenrequest.html#QtGadgetHelper-typedef
