For x86 it is better to send it to one CPU only.

This introduces an NMI (non maskable interrupt) callback per CPU class
which QMP's "nmi" command may use to issue NMI on a CPU.
This adds support for it in qmp_inject_nmi(). Since no architecture
supports it at the moment, there is no change in behaviour.
