* Refactors z level trait checking to be less shit (#69334)
* Puts level traits and their associated z into a list and then uses it to make the z level trait procs less shit. They no longer need to loop through every z level to do what they aim to do.
* Also removes get_level from level_trait because it just does the same checks as already done above in the proc.
