SQL/ODBC: properly set SQL_ATTR_CURSOR_SCROLLABLE

Browse Source 
Setting a query in forward-only or scrollable mode was done with
SQL_ATTR_CURSOR_TYPE in ODBCv2. Nearly all ODBCv3 drivers also honor
this value but some don't and need the ODBC v3 conformant
SQL_ATTR_CURSOR_SCROLLABLE attribute instead. Fix it by setting both
attributes.

Fixes: QTBUG-126118
Pick-to: 6.7 6.5
