Backport #24105 by @lunny In #12269, all string fields of struct will generate a NVARCHAR column in database, but for those Gitea instances installed before that PR, users have to convert columns themselves. In this PR, we update the `./gitea admin convert` commands to support both MySQL and MSSQL database converting. Previously, it only supported converting `utf8 -> utf8mb4` for MySQL. Now, it will check the database types. If it's MSSQL, it will convert `VARCHAR -> NVARCHAR` as well. Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
