Fixes the main part of https://github.com/ppy/osu/issues/31144.
Support for selecting a video will come later.
Making this work was an absolutely awful time full of dealing with
delightfully kooky issues, and yielded in a very weird-shaped
contraption. There is at least one issue remaining wherein storyboard
videos do not actually display until the track is started in editor, but
that is 99% a framework issue and I do not currently have the mental
fortitude to diagnose further.
Would close https://github.com/ppy/osu/issues/31312.
Not super happy with the performance overhead of this, but this is
already a heuristic-based implementation to avoid every-frame
`.ChildrenOfType<>()` calls or similar, so not super sure how to do
better. The `Array.Contains()` check stands out in profiling, but
without it the indicators can collapse *too* eagerly sometimes.

The reason why I opted for a complete rewrite rather than a revival of
that aforementioned pull series is that it always felt quite gross to me
to be pulling framework's audio subsystem into the task of reading ID3
tags, and I also partially don't believe that BASS is *good* at reading
ID3 tags. Meanwhile, we already have another library pulled in that is
*explicitly* intended for reading multimedia metadata, and using it
does not require framework changes. (And it was pulled in explicitly for
use in the editor verify tab as well.)
The hard and dumb part of this diff is hacking the gibson such that
the metadata section on setup screen actually *updates itself*
after the resources section is done doing its thing. After significant
gnashing of teeth I just did the bare minimum to make work by caching
a common parent and exposing an `Action?` on it. If anyone has better
ideas, I'm all ears.

Tend to agree that this is a good idea for gameplay test at least. Not
sure about other similar interactions like exiting - I don't think it
matters what's done in those cases, because for exiting timing is in no
way key, so I just applied this locally to gameplay test.
This was very weird on master - `ModDisplay` applied a fade-in on the
`iconsContainer` that lasted 1000ms, and `HUDOverlay` would stack
another 200ms fade-in on top if a replay was loaded. Moving that first
fadeout to a higher level broke fade-out because transforms got
overwritten.
