improve timings for S variants of multiply instructions on arm9

behavior seems to be a quirk of the way they made the interlock cycle mandatory

revert the *entire* interlock implemention

too slow, not accurate enough.
we need to do a *lot* more research into the specifics of how this works with all the various aspects of the cpu's timings before we can make a good implementation

updating console, fixes crash on console type switch
EmuInstance::consoleType is already updated, so the check for whether we
should recreate the NDS to switch console type never succeeds.

non-exhaustive (but exhausting) list of changes:
