sim: sim_cpu: invert sim_cpu storage
Currently all ports have to declare sim_cpu themselves in their sim-main.h and then embed the common sim_cpu_base in it. This dynamic makes it impossible to share common object code among multiple ports because the core data structure is always different. Let's invert this relationship: common code declares sim_cpu, and the port uses the new arch_data field for its per-cpu state. This is the first in a series of changes: it adds a define to select between the old & new layouts, then converts all the ports that don't need custom state over to the new layout. This includes mn10300 that, while it defines custom fields in its cpu struct, never uses them.
