sql: disallow explicit unique checks under read committed isolation #110879

  1. sql: disallow explicit unique checks under read committed isolation 

    Because we do not yet support predicate locking, add a check to
execbuilder that disallows any query using it (currently only unique
checks under read committed isolation).

Informs: cockroachdb#110873

Release note (sql): We do not yet support explicit unique checks under
Read Committed isolation. This means that some `INSERT`, `UPDATE`, and
`UPSERT` statements against some `REGIONAL BY ROW` tables will fail
under Read Committed isolation with the following error:

```
unimplemented: explicit unique checks are not yet supported under read committed isolation
SQLSTATE: 0A000
```

For more details about which `REGIONAL BY ROW` tables are affected,
please see: https://go.crdb.dev/issue-v/110873/v23.2
