QString: add QStringView/QLatin1String overload of (non-multi) arg()

Use the new overload directly in QXmlStream*.

Saves 129B in QtCore text size on optimized GCC 6.1 Linux AMD64
builds, even though we added two more functions.

[ChangeLog][QtCore][QString] Added arg(QStringView),
arg(QLatin1String) overloads.
