Handle DELETE with LIMIT in Arel
MySQL supports DELETE with LIMIT and ORDER BY.
https://dev.mysql.com/doc/refman/8.0/en/delete.html
Before:
```
Post Destroy (1.0ms) DELETE FROM `posts` WHERE `posts`.`id` IN (SELECT `id` FROM (SELECT `posts`.`id` FROM `posts` WHERE `posts`.`author_id` = ? ORDER BY `posts`.`id` ASC LIMIT ?) __active_record_temp) [["author_id", 1], ["LIMIT", 1]]
```
After:
```
Post Destroy (0.4ms) DELETE FROM `posts` WHERE `posts`.`author_id` = ? ORDER BY `posts`.`id` ASC LIMIT ? [["author_id", 1], ["LIMIT", 1]]
```
