arch,cpu,base: Make add a virtual method to stutter the PC for KVM.

As described in a comment in the base KVM CPU, there needs to be a way
to set the next PC of a PCState object to the actual current PC. Since
this is the only place that sort of operation is needed and it's a bit
of a hack to get around a quirk of calling pseudo instructions in a KVM
CPU, we can support it by adding a virtual method for it which is
implemented by the ISA specific subclasses of the KVM CPU.
