When multiple admins are working in the review queue, it's quite easy for two people to try and handle the same reviewable at the same time. This change addresses the two major situations where this can occur.
The `ReviewableClaimedTopic` model has been extended to allow the system to mark a reviewable as claimed as soon as the first moderator starts handling the reviewable, even when the `reviewable_claiming` setting is disabled. This ensures that reviewable actions with client-site activity (for example, `agree_and_suspend`) will lock the reviewable before another moderator starts working on it.
When someone handles handles a reviewable, we now use `MessageBus` to inform other moderators that it's changed. If any of the other moderator have that reviewable open (either individually, or on the list screen), it will automatically refresh that data.
Currently, categories support designating only 1 group as a moderation group on the category. This commit removes the one group limitation and makes it possible to designate multiple groups as mods on a category.

The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
This new site setting replaces the
`enable_experimental_sidebar_hamburger` and `enable_sidebar` site
settings as the sidebar feature exits the experimental phase.
Note that we're replacing this without depreciation since the previous
site setting was considered experimental.

Users who can access the review queue can claim a pending reviewable(s) which means that the claimed reviewable(s) can only be handled by the user who claimed it. Currently, we show claimed reviewables in the user menu, but this can be annoying for other reviewers because they can't do anything about a reviewable claimed by someone. So this PR makes sure that we only show in the user menu reviewables that are claimed by nobody or claimed by the current user.

I'm hesitant to call this a performance improvement since claiming a
reviewable is probably rare. However, this commit cuts out two DB
queries each time we have to publish a reviewable claimed message. More
importantly, publishing to groups scales much better than publishing to
users because we esstentially cap the number ids we have to load into
memory.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
This is a feature that used to be present in discourse-assign but is
much easier to implement in core. It also allows a topic to be assigned
without it claiming for review and vice versa and allows it to work with
category group reviewers.
