[liftoff] Mark unused parameters per platform 

Many platform-dependent LiftoffAssembler methods do not use all
parameters. Comment out the name of unused ones, to make it easier to
see which implementation uses which parameters.

Also, remove {is_load_mem} from arm's {LoadInternal}, because it is
unused there.
