FEATURE: Update upload security status on post move, topic conversion, category change (#8731) 
Add TopicUploadSecurityManager to handle post moves. When a post moves around or a topic changes between categories and public/private message status the uploads connected to posts in the topic need to have their secure status updated, depending on the security context the topic now lives in.

2c011252f1 FIX: Move notification level only when user posted 
Moving posts also moves the read state (`topic_users` table) to the destination topic. This changes that behavior so that only users who posted in the destination topic will have the original notification level (probably "watching") of the original topic. The notification level for all other users will be set to "regular".

f1742617fb PERF: Faster moving of read state 
This should improve the performance of moving the read state of lots of posts to a new/existing topic.

10e509e47f FIX: Don't swallow the original error when moving posts 
Dropping the temp table in an `ensure` block hides the actual exception. Creating the table with `ON COMMIT DROP` makes the temp table disappear automatically at the end of the transaction. We only need the explicit `DROP` in tests, because tests already run inside a transaction, so the temp table won't be dropped after each test which leads to spec failures.

bee000bcec FIX: Existing post timings could prevent moving posts 
Post timings are created by `topic_id` and `post_number` and it's possible that the destination topic already contains post timings for non-existent posts. For example, this can happen if the destination topic was previously split and Discourse recorded post timings for moved posts in the destination topic.

This commit ensures that all timings which reference non-existent posts are deleted from the destination topic before the posts are moved.

2a95c5c5d6 FIX: Don't update watching_first_post notifications when moving first post 
The first post isn't moved. It gets copied during a move. Notifications of this special type should still link to the original first post.

271ddac467 FIX: Delete notifications users can't see after moving posts 
No need to let notifications stay around when users can't access
a topic after it was converted into a PM or posts were moved
into a restricted topic.

Also makes sure that moving to a new topic correctly uses the
guardian for the first post by enqueuing jobs outside of a
transaction.

30990006a9 DEV: enable frozen string literal on all files 
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

FIX: Do not move hidden post actions. (#7424) 
Hidden (staff-only) post actions are whisper posts with no content, that
are later transformed by the client into post actions (discourse-assign
uses this).
