Customizable note hit sounds & effects

[FlooferLand]

This PR adds note hit sound effects, as well as a little sound system for playing general note-related sounds.
It also adds a settings toggle for note splash particles, as requested by a // TODO I saw.

See FunkinCrew/funkin.assets/preload/sounds/noteSounds/how to.txt to see how to add new sounds

This PR was previously #2793.
Made a new PR as I rewrote everything and the old PR contained remnants of the new settings widget system

I always forget about the develop branch, my bad.

Not sure how to change my fork / local repo over to the develop branch without risking accidentally nuking the entire PR again, I think I give the lead maintainers a heart attack any time they see me do anything with git lmao

Also, I solved a conflict and someone added a showNotesplash to Strumline.hx, but it doesn't seem to be used by anything?

Just start the branch using the develop one as a base, rather than main. Then, when you make the PR, make sure you're requesting to merge into the develop branch and you should be fine!

Also, if you click the dropdown of the conflict fix thing below when there's a conflict, you can choose to rebase it rather than merge to keep the commits clean.

If you plan to continue working on the PR/branch after that, make sure that you pull the rebased branch from your remote origin of the branch first.

showNotesplash is for mods. It's so that mods can disable/enable note splashes at will. (See #4009)
