Fixes a bunch of invalid icon states. There's more, but my brain isn't fried enough for that. (#58608)

gibup1 and gibdown1 don't exist
items_and_weapons.dmi doesn't have an icon state called his_grace_ascended, in fact nothing does
items_cyborg.dmi doesn't have an icon state called laser, it  does however have an icon state called
laser_cyborg
no porta_turret has an icon state with the _unpowered suffix, in fact I'm convinced none of them ever have
