CPU profiling on workloads with intensive vtophys operations (i.e. very small CB-DMA transfers) exposed overhead introduce by spdk_vtophys having to call spdk_mem_map_translate in a different compilation unit. Let's just move the vtophys.c contents into memory.c so that spdk_vtophys can inline spdk_mem_map_translate and avoid this extra overhead. This of course breaks the memory and vtophys unit tests, so some additional changes are needed there to keep everything linking correctly.
