Port the QXmlStream API from QStringRef to QStringView

Browse Source 
This gives some source incompatibilities, most of them can be
handled by using auto instead of QStringRef explicitly.

[ChangeLog][Important API changes] QXmlStream now uses QStringView
insteead of QStringRef in it's API. Using auto forvariables returning
a QStringRef in Qt 5 should lead to code that can be used against both
Qt versions.

Fixes: QTBUG-84317
