sim: watchpoints: change sizeof_pc to sizeof(sim_cia)
Existing ports already have sizeof_pc set to the same size as sim_cia, so simply make that part of the core code. We already assume this in places by way of sim_pc_{get,set}, and this is how it's documented in the sim-base.h API. There is code to allow sims to pick different register word sizes from address sizes, but most ports use the defaults for both (32-bits), and the few that support multiple register sizes never change the address size (so address defaults to register). I can't think of any machine where the register hardware size would be larger than the address word size either. We have ABIs that behave that way (e.g. x32), but the hardware is still equivalent register sized.
