Minor code refactoring

Some methods in ConfigLoaderHandler always returned true, change them to return
void instead. Also port them to take a QStringView instead of QStringRef, this
doesn't require a lot of changes because a QStringView can be constructed from
a QStringRef.

QXmlStreamAttribute methods like value() and name() return QStringRef in Qt5
and QStringView in Qt6, "fix" the issue by using auto keyword, which works
in both cases.

QStringView::toInt() isn't efficient in Qt5 so make the build conditional.
