Support `IN BOOLEAN MODE` full-text search syntax (for Mediawiki)

Mediawiki uses [MySQL's `IN BOOLEAN MODE` for boolean full-text searches](https://dev.mysql.com/doc/refman/8.0/en/fulltext-boolean.html), but because Dolt doesn't support that, Mediawiki's search functionality doesn't work when running on Dolt.

Here's the error from Dolt's logs:
```
