Old versions of the Mattermost server did not qualify queries scanning both `Posts` and `Threads`, and choke on the ambiguity in deciding between the new `DeleteAt` on `Threads` and the `DeleteAt` on `Posts` in existing queries.
While this problem is transient only while running multiple server versions, it effectively makes our backwards compatibility guarantee void, not to mention complicating cloud deployments.
Work around this by renaming `Threads.DeleteAt` to `Threads.ThreadDeleteAt`. The old migration is nulled out, but remains, since some test servers have already upgraded and manually fixing each affected instance would be problematic. Thew new migration takes care of removing the old column -- if it ever existed.

* MM-40148: threadsOnly query param for user threads
Currently we always calculate counts when fetching user threads.
Those counts include total, unread replies, and unread mentions,
and are potentially expensive to calculate.
This commit adds a new query param 'threadsOnly' which won't calculate
any counts and just return threads.

* deadcode: remove UpdateChannelLastViewedAt
* deadcode: remove ThreadStore.(Save(Multiple)|Update|Delete)
* deadcode: followThead in App.MarkChannelAsUnreadFromPost
* document ThreadMembership, Thread structs
* maintain LastUpdated consistently
Whenever we touch a `ThreadMembership` record, we should be setting `LastUpdated` to the current timestamp. The mobile client relies on this to detect changes to these records.
* simplify: never updateThreads from `App.MarkChannelAsUnreadFromPost`
Change all invocations of `ChannelStore.UpdateLastViewedAtPost` from `App.MarkChannelAsUnreadFromPost` to pass `updateThreads` as `false`. When `ChannelStore.UpdateLastViewedAtPost` was invoked with `updateThreads` as `true`, it would in turn call `ThreadStore.UpdateUnreadsByChannel` but pass `updateViewedTimestamp` as `false`. This effectively updated the `LastUpdated` field of the corresponding thread memberships but never touched any of the actual data (such as `LastViewed`).
The overall CRT feature continued to work, because `App.MarkChannelAsUnreadFromPost` directly updates the relevant thread memberships via `ThreadStore.MaintainMembership`.
* deadcode: updateThreads in ChannelStore.UpdateLastViewedAtPost
* simplify: never updateThreads from App.SendNotifications
Change all invocations of `ChannelStore.IncrementMentionCount` from
`App.SendNotifications` to pass `updateThreads` as `false`. When `ChannelStore.IncrementMentionCount` was invoked with `updateThreads` as `true`, it would in turn call `ThreadStore.UpdateUnreadsByChannel` but pass `updateViewedTimestamp` as `false`. This effectively updated the `LastUpdated` field of the corresponding thread memberships but never touched any of the actual data (such as `UnreadMentions`).
The overall CRT feature continued to work, because `App.SendNotifications` directly updates the relevant thread memberships mention counts via `ThreadStore.MaintainMembership`.
* deadcode: updateThreads in ChannelStore.IncrementMentionCount
* fix & rename ThreadStore.UpdateUnreadsByChannel
Rename `ThreadStore.UpdateUnreadsByChannel` to `ThreadStore.UpdateLastViewedByThreadIds`, making it unconditionally set the `LastViewed` for the given threads (as well as `LastUpdated`).
All previous invocations of this method that passed `updateViewedTimestamp` have been previously removed.
