Column rename through `CHANGE COLUMN` changes column order

[Luit]

Version

1.14.0

What happened?

After I noticed #1605 was added to 1.14 I ran the new version against our code, as I know there's a few CHANGE COLUMN statements in there. I noticed the ones that don't change the name are also impacted by this change, as they're pulled down to the last position in the column list it seems.

I only tested this with our own code against a MariaDB. In my case, column order doesn't change when CHANGE COLUMN is used to change type, change name, or both.

@Luit What impact does the ordering of the columns have on your queries?

[Luit]

I noticed this caused a diff on my structs even though nothing functionally changed. I'm not entirely sure whether sqlc actually maintains column order similar to how MariaDB(/MySQL) does this, but so far column order and struct order was the same for our cases. If ADD COLUMN x AFTER y doesn't have an impact on struct order either, then I'm not sure this one is important either.
