This change refactors `GetAdjustedDisplayDifficulty()` and
`GetBeatmapAttributesToDisplay()` in two ways:
- Both methods now accept `IBeatmapInfo` instead of
`IBeatmapDifficultyInfo`. This is done in order to make mania key
count display to work, wherein `IBeatmapDifficultyInfo` is not enough
to calculate the final key count.
- `GetAdjustedDisplayDifficulty()` now applies all
`IApplicableToDifficulty` mods itself. I did this after noticing that
every real consumer of this method had to do that themselves for very
little reason.
In stable mania, Hard Rock and Easy mods do not work the same way as
they do on all of the rulesets. The difference is that mania HR and EZ,
rather than apply a multiplier to the map's original Overall Difficulty,
apply multipliers to *the durations of hit windows themselves*.
Prior to the last release, lazer was oblivious to this reality and just
treated mania HR / EZ as it did every other ruleset. Last release, for
the sake for gameplay parity across rulesets, the mods in question were
adjusted to match stable, but in the process, it started looking like HR
/ EZ did not change OD anymore.
The problem is that they do, but applying a multiplier to the map's OD
and applying a multiplier to the hit window duration is not the same
thing. The second thing is actually *much harsher* in magnitude, to the
point where applying HR to any map is almost guaranteed to exceed "the
effective OD" of 10, and applying EZ to any map is almost guaranteed to
result in "negative effective OD".
This change attempts to convey that reality by displaying "effective
OD", similar to what's already done in other rulesets when rate-changing
mods are active. Note that the values this will display *do not match*
stable *and that is correct*, because stable song select *lies* about
the actual impact on OD by just assuming it can treat all rulesets in
the same way.

Would close https://github.com/ppy/osu/issues/34150 I guess.
And yes I would like *all of the above* to land on the changelog if
possible if this is merged.
For further convincing that this makes any semblance of sense please see

Mods don't necessarily have to change speed, to change beatmap attributes. Also, speed mods don't affect beatmap attributes in mania, making the text misleading.
Saves having this defined in 20+ places. If we ever make any changes to
shear, it's 100% going to need to be applied to every usage (there will
never be a case of multiple different shears in the game).
Also fixes a mismatching definition in `ShearedNub`.
It was quite easy to dismiss by accident. I've added some positional and
time based lenience with numbers that feel good to me. Open to
discussion on whether both are required and if the numbers feel good.
Going forward, at some point, we'll likely want to standardise this
across to other expand-on-hover elements (like player load overlays).
