epriestley d67b7f0f47 Correct column mutations for old versions of MySQL
Summary:
Ref T1191. Although I fixed some of the mutations earlier (in D10598), I missed the column mutations under old versions of MySQL. In particular, this isn't valid:

  - `ALTER TABLE ... MODIFY columnName VARCHAR(64) COLLATE binary`

Issue the permitted version of this instead, which is:

  - `ALTER TABLE ... MODIFY columnName VARBINARY(64)`

Also fixed an issue where a clean schema had the wrong nullability for a column in the draft table. Force it to the expected nullability.

The other trick here is around the one column with a FULLTEXT index on it, which needs a little massaging.

Test Plan:
  - Forced my local install to return `false` for utf8mb4 support.
  - Did a clean adjust into `binary` columns.
  - Poked around, added emoji to things.
  - Reverted the fake check and did a clean adjust into `utf8mb4` columns.
  - Emoji survived.
