QSqlQuery: Add QStringView overloads

Add an overload to QSqlQuery::isNull()/::value() taking a QStringView -
those two functions can now use the newly introduced
QSqlRecord::indexOf(QStringView)

[ChangeLog][QtSql][QSqlRecord] QSqlQuery::isNull() and value() gained a
new overload taking a QStringView.
