kernel/process: Make CodeSet a regular non-inherited object
These only exist to ferry data into a Process instance and end up going out of scope quite early. Because of this, we can just make it a plain struct for holding things and just std::move it into the relevant function. There's no need to make this inherit from the kernel's Object type.
