QMetaObject: consistently use QByteArray(View) in the implementation

Browse Source 
The implementation was inconsistent.
The `stringData()` method was returning QByteArray, while
the `stringDataView()` method was returning QLatin1StringView.
Update the second method to return QByteArrayView instead, and fix all
related places.

Found while trying to resolve ambiguities in QL1SV <-> QBAV comparison.
