Increase bootcamp code columns from TEXT to MEDIUMTEXT

The `code` column on bootcamp_submissions, bootcamp_solutions, and
bootcamp_drawings used MySQL TEXT (64KB with utf8mb4), which is too
small for some user submissions. Upgrade to MEDIUMTEXT (16MB) to
prevent ActiveRecord::ValueTooLong errors.

Closes #8483
