arch, mem: Make the page table lookup function return a pointer.
This avoids having a copy in the lookup function itself, and the declaration of a lot of temporary TLB entry pointers in callers. The gpu TLB seems to have had the most dependence on the original signature of the lookup function, partially because it was relying on a somewhat unsafe copy to a TLB entry using a base class pointer type.
