Remove obsolete namespace documentation

That there is a 'using namespace QtDataVisualization' statement in the
'galaxy' manual tests suggests that there used to be one, but there isn't
anymore.

This documentation appears to have been for that long-gone namespace, so
remove it to silence qdoc. Fix references to the now global
qDefaultSurfaceFormat utility function.

Pick-to: 6.1

+  \c {qDefaultSurfaceFormat()}).
   This rendering mode offers the best performance at the expense of non-standard QML behavior. For example,
   the graphs do not obey the z ordering of QML items and the opacity value has no effect on them.
