[ENHANCEMENT] Stop strumline hold splash on Bot Play / Opponent, Allow character metadata to control icon "bop"

[pahaze]

Description

I noticed a few things that I thought would be nice to be enhanced, namely disabling the opponent's strumline (and, your strumline during Bot Play) hold note splash, and allowing character metadata to control the ability to have their icon bop or not.

The former is something I just had a pet peeve with since it doesn't play the final splash after the hold notes are finished. The latter is something I personally saw fit to be fixed as I was playing around with porting some older mods, and having the ability to use animated icons OOTB now is incredibly nice, but the bop missing just felt wrong.

Sidenote

There's also an absolutely tiny change in the FunkinMemory that I just thought looked nicer. It just changes how the combo numbers are loaded to a for loop rather than doing 1, 2, 3, etc etc manually.
Also sorry about my horrid commit from a few years back, I was 14 and barely knew anything about coding, let alone the idea of animated sprites lol
