The whole component is pointless so I'm just going to nuke for now I
guess. Kind of makes the whole refactor effort pointless but oh well?
To expand on this, the implementation was actually incorrect as pointed
out at https://github.com/ppy/osu/pull/18819#pullrequestreview-1017886035.
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:

I kinda liked this flow, but from multiple reports from users it
definitely seems in the way. We can revisit after the new design is
applied to song select.
Note that this means the tooltips also don't display. If it is preferred
that they should (arguable from a UX perspective, since I'd expect to be
able to click at that point) then the issue can be addressed using a
slightly different path (a few more lines - nothing too complex).
Even with pooling applied, there are overheads involved with transforms
when quickly cycling through the carousel.
The main goal here is to reduce the transforms in cases the reuse is
still in the same state. Avoiding firing `FadeIn` and `FadeOut` are the
main areas of saving.
