Add UB-free implementations of RBA and BA

[Rozelette]

This adds native, UB-free implementations of RBA and BA. In addition, this makes RBA work off of C right, like vanilla. I have removed the RestoreRBAValues setting because it doesn't really make sense anymore. We should have vanilla behavior by default, and if there is a demand for our old RBA behavior, that should be implemented as a new, opt-in setting.

There is a slight deviation from vanilla behavior. ITEM_SONG_NOCTURNE and ITEM_SONG_PRELUDE read and write to padding bytes in the save struct. Theoretically, you could use BA to write a value to them, then read it with RBA. This would be a more complicated thing to implement since it'll add new fields in the save struct. I couldn't find any actual use of this behavior in speedruns or rando tricks, so I've elected to not fully implement it.

This fixes #4214
