[sql] Consider removing the `SetDbStatementForText` configuration option

[alanwest]

SetDbStatementForText controls setting db.query.summary and a sanitized version of db.query.text. The option is currently disabled by default.

db.query.summary and db.query.text are required by the semantic conventions. I propose we eliminate this configuration option. Other languages supporting these attributes have not provided a way to opt in or out of this functionality.
