We now have a couple of global.h headers that do only start with 'q'.
We can't change this anymore, so let's just accommodate for that.
This fixes the following warnings
qtserialport/src/serialport/qserialportglobal.h does not include QT_BEGIN_NAMESPACE
qtwebsockets/src/websockets/qwebsockets_global.h does not include QT_BEGIN_NAMESPACE
qtwebchannel/src/webchannel/qwebchannelglobal.h does not include QT_BEGIN_NAMESPACE
Pick-to: 6.2
Fixes: QTBUG-97831
