Support for MariaDB's RETURNING clause

[Jille]

What do you want to change?

MariaDB 10.5.0 has added INSERT INTO .. RETURNING like PostgreSQL supports.

https://mariadb.com/kb/en/insertreturning/

DELETE .. RETURNING is also supported, but UPDATE .. RETURNING not yet.

github.com/pingcap/tidb/pkg/parser doesn't seem to support it.
