cpus: pass CPUState to run_on_cpu helpers

Browse Source 
CPUState is a fairly common pointer to pass to these helpers. This means
if you need other arguments for the async_run_on_cpu case you end up
having to do a g_malloc to stuff additional data into the routine. For
the current users this isn't a massive deal but for MTTCG this gets
cumbersome when the only other parameter is often an address.

This adds the typedef run_on_cpu_func for helper functions which has an
explicit CPUState * passed as the first parameter. All the users of
run_on_cpu and async_run_on_cpu have had their helpers updated to use
CPUState where available.

[Sergey Fedorov:
 - eliminate more CPUState in user data;
 - remove unnecessary user data passing;
 - fix target-s390x/kvm.c and target-s390x/misc_helper.c]
