Gary Pendergast 096b09d941 dbDelta: Ignore index subparts when checking for duplicate indices. ...

If index lengths change in table definitions, we don't recreate the index - instead, we throw a database error, as `dbDelta()` tries to create a new index with the same name.

It's better to leave the index as is, MySQL doesn't have an efficient process for resizing indices, and dropping/creating is a slow process which we don't want to trigger automatically.

Fixes #34870.
