Add configuration option to disable Taiko notes flying after hit

[aedoq]

In osu!stable, the "flying away" animation is shown only when the HUD is active. This adds a configuration option to restore this behaviour or to disable the animation altogether.

Discussed previously: #23656

Just a personal opinion as a taiko player, I like this but it feels like the fade effect takes too long, I feel like I'm hitting late because the note disappears late. For comparison, stable faded the notes instantly.

@LittleLilyBun You're right, I changed this to be the same as in stable, should be less jarring:

As an aside, I made a somewhat related pull request about a year ago addressing the animation of the flying notes not snapping to the center of the judgement area like they do in stable: #26926

Perhaps these two features could be combined together into a single setting as they both relate to the appearance of the flying notes?

Would wait on the thoughts of a maintainer before making any changes.

I'm not going to make a call on this one because this is something that would've been addressed by ruleset skinning. Will defer to @peppy.
