Summary:
Ref T11741. InnoDB uses a stopwords table instead of a stopwords file.
During `storage upgrade`, synchronize the table from the stopwords file on disk.
Test Plan:
- Ran `storage upgrade`.
- Ran `select * from stopwords`, saw stopwords.
- Added some garbage to the table.
- Ran `storage upgrade`, saw it remove it.
