Until now UpdateStateTransforms was applying results offsets to
StartTime. This didn't cover the case of a HitObject with duration,
where the call would be made with `StartTime + hitOffset` rather than
`EndTime + hitOffset`.
To resolve this, a new method has been added which should be used to
handle hit-specific state transforms.
We've seen multiple cases where DrawableHitObject are stuck in the lifetime management container
due to not implementing a judgement (meaning they are never "hit" or "missed"). To avoid this going forward
CreateJudgement() must be implemented and return a non-null judgement.
This fixes BananaShower and JuiceStreams in osu!catch.
This also makes HitObject abstract and cleans up convert HitObject implementations.
