* MM-24135: Migrate AppError from SaveChannel/channel_store.go This is the first POC of migration of store app errors to plain error. We create a few basic error types in the store package and use them to return the errors from store methods. In the app layer, we inspect the error and re-create the exact app errors. This lets us preserve the same error content, but yet move to plain errors. Since this is a gradual migration, this means that the error inspection code will be duplicated across the app layer whenever a store method is invoked. But all of that should go away once we start propagating the errors higher up the hierarchy. There have been a significant amount of changes in the storetest and searchtest layer, primarily because we have to rename the err variable now that it is of a different type. * Addressed review comments * Made all appError origins to be CreateChannel * Remove typed internal error * Fix translations * fix layer generation Co-authored-by: mattermod <mattermod@users.noreply.github.com>
