QMetaObject: save a strlen() in typeFromTypeInfo()

Browse Source 
QMetaType::fromName() takes a QBAV, so don't feed it rawStringData()
(a const char*, causing the QBAV ctor to run strlen() on it), but
stringDataView() (a QBAV already, whose length is determined by offset
difference in the string offset table and not by strlen()).

No measurable difference in runtime speed.

Pick-to: 6.9 6.8 6.5
