kernel/vm_manager: Rename CodeStatic/CodeMutable to Code and CodeData respectively

Makes it more evident that one is for actual code and one is for actual
data. Mutable and static are less than ideal terms here, because
read-only data is technically not mutable, but we were mapping it with
that label.
