Previously setting `enable_order_by_all` distinguished for ORDER BY ALL
whether we should sort by column 'all' (if given in the SELECT clause)
or by all columns. The actual behavior was not always intuitive.
Now, we throw unconditionally an exception which also simplifies the
handling a bit. Only an edge case is affected and if users really want
to run ORDER BY ALL on a column names 'all', they can alias it.
