This commit is a major overhaul of how chat message actions work, to make it so they are reusable between the main chat channel and the chat thread panel, as well as many improvements and fixes for the thread panel.
There are now several new classes and concepts:
* ChatMessageInteractor - This is initialized from the ChatMessage, ChatMessageActionsDesktop, and ChatMessageActionsMobile components. This handles permissions about what actions can be done for each
message based on the context (thread or channel), handles the actions themselves (e.g. copyLink, delete, edit),
and interacts with the pane of the current context to modify the UI
* ChatChannelThreadPane and ChatChannelPane services - This represents the UI context which contains the
messages, and are mostly used for state management for things like message selection.
* ChatChannelThreadComposer and ChatChannelComposer - This handles interaction between the pane, the
message actions, and the composer, dealing with reply and edit message state.
* Scrolling logic for the messages has now been moved to a helper so it can be shared between the main channel pane and the thread pane
* Various improvements with the emoji picker on both mobile and desktop. The DOM node of each component is now located outside of the message which prevents a large range of issues.
The thread panel now also works in the chat drawer, and the thread messages have less
actions than the main panel, since some do not make sense there (e.g. moving messages to
a different channel). The thread panel title, excerpt, and message sender have also been removed
for now to save space.
This gives us a solid base to keep expanding on and fixing up threads. Subsequent PRs will
make the thread MessageBus subscriptions work and disable echo mode
for the initial release of threads.

On mobile, we just need to add `min-width: 0` to
`chat-live-pane` so it will not overflow the grid
defined in `main-chat-outlet.chat-view`.
The overflow could be triggered by:
1. Replying on mobile to a really long chat message
2. Uploading > 2 files
Both of these situations are fixed.
This css was causing the view on mobile to take more space than the available width. This was particularly visible with uploads due to a bug preventing the overflow, this is also fixed.
This commit introduces the skeleton of the chat thread UI. The
structure of the components looks like this. Its done this way
so the side panel can be used for other things as well if we wish,
not just for threads:
```
.main-chat-outlet
<ChatLivePane />
<ChatSidePanel>
<-- rendered with {{outlet}} -->
<ChatThread />
</ChatSidePanel>
```
Later on the `ChatThreadList` will be rendered here as well.
Now, when you go to a channel you can open a thread by clicking
on either the Open Thread message action button or by clicking on
the reply indicator. This will take you to a route like `chat/c/:slug/:channelId/t/:threadId`.
This works on mobile as well.
This commit includes basic serializers and routes for threads,
as well as a new `ChatThreadsManager` service in JS that caches
threads for a channel the same way the channel threads manager does.
The chat messages inside the thread are intentionally left out
until a later PR.
**NOTE: These changes are gated behind the site setting enable_experimental_chat_threaded_discussions
and the threading_enabled boolean on a ChatChannel**
