move checksum self check variables to a place they are not likely to get clobbered update bank / ram usage notes update ram clearing method for more performance. change ram clear method cannot math clear ram via dma (leave our variables in place)

Holding off on merging this until we can get more information on how this affects the FXPAK, e.g. if it makes the in-game hooks work properly without still causing other forms of corruption. If the alternative is some other, more subtle type of corruption, the concern is that it could be worse than just getting an error. We also may want to look at what happens with the RTA timer, since the RTA timer starts counting early in bootup process, and I forget what if anything we did to avoid it being affected the RAM clearing. |

i'll look into the RTA timer, might be worth asking in the general discord for those who play with fxpak /s2snes if they .. a. use ingame hooks. |

move checksum self check variables to a place they are not likely to get clobbered by the unsafe behaviour of sd2snes/fxpak menus/ingame hooks / savestates
(this feature might overwrite other variables that were around where the old checksum variables used to be) but having a hard crashing routine highlighted this problem.
move and re-write common boot bank 7e clear routine to not wipe our variable.. this uses dma now which is 66% faster than the original part unrolled stz routine (0336-033f) are preserved.
