Test failed locally in `TestPublicChannelMention`. This test seems to
specify that the same message may arrive twice with the same ID, so
rather than overthinking this one I propose we just use `FirstOrDefault`.

Adds new component `ChannelControlItem` and it's child components to be
used as the clickable control in the new chat sidebar for joined
channels.
Has public properties `HasUnread` and `MentionCount` to control the
display of the channel having unread messages or mentions of the user.
Channel select/join requests are exposed via `OnRequestSelect` and
`OnRequestLeave` events respectively which should be handled by a parent
component.
Requires a cached `Bindable<Channel>` instance to be managed by a parent
component.
Requires a cached `OveralayColourScheme` instance to be provided by a
parent component.
The equality of samples is generally used to compare the sample
equality, not its full properties. For instance, we don't compare
`Volume` in the base implementation.
Having `IsLayered` here breaks actual usages of equality, ie. for
pooling purposes.
Without this change, there would be a couple of pixels between each list
item where nothing would be hovered. This is a pretty annoying UX which
we should be avoiding we possible.
Also removes the necessity of scheduling as it actually never worked as
intended, `Scheduler` will still update even when the chat line is
masked away, and the animation will never be held anyways.
The new duration of the animation should be enough for long scrolls
either way.
In the case a message arrives and the chat overlay is hidden, clicking
on the mention notification will not work as the `HighlightedMessage`
bindable callback will execute before the scheduled `newMessagesArrived`
logic (which was hanging since the message arrived until the chat
overlay became open because of the notification).
Simplify things by always scheduling the `HighlightedMessage` bindable
callback.
As seen by this kind of crash, having the `.ToMod` method throw can be
very problematic and also hidden (as it is used inside of models in
places where exceptions are not expected to occur).
Given there are tens of usages of this method, returning a placeholder
mod seems like a better idea than outright throwing.

This is an issue as carousel panels manage their own animated state. If
they are marked as not-visible (done at a higher level, from filtering
or update pathways) but clicked while fading out, they will animate back
to a visible state but not be marked as visible.
No tests for this one as it's probably not worthwhile to test (and hard
to do so). Manual testing can be done with the following patch:
