[MM-63196] Channel sql store migrate select * to specific columns (#30255)

* Adde MySQL and Postgres migrations

* Replaced select * with column names

* removed all * from channel SQL store

* cleanup

* Fixed a duplicate column

* cleanup

* used channelname slice in a missed place

* WIP

* converted to query builder

* cleanupo

* Review fixes
