Subject: [PATCH] roachtest: add SQLsmith roachtest

This add a new nightly roachtest that run SQLsmith against the latest master
looking for panics.

If this crashes, the cause of the crash can be found in the logs for the first
(and only) node.

This test is being checked in as a skip due to #32270.

Release note: None
