12 GiB heap crash workaround

Browse source 
Using resolution mods, heaps past 8 GiB work in some games (like LoZ: TotK) and not in others (like SMP Jamboree). Setting the heap to a hard limit of 8 GiB on the 10 & 12 GiB DRAM options seems to be the safe bet right now until a better solution is found.
