Reduce 'd' debug key's global impact

the state dumping logic to alternatively block each CPU as it prints

handling toggle introduced with an earlier patch).

Further, instead of using on_selected_cpus(), which is unsafe when
the dumping happens from a hardware interrupt, introduce and use a
dedicated IPI sending function (which each architecture can implement
to its liking)

Finally, don't print useless data (e.g. the hypervisor context of the
interrupt that is used for triggering the printing, but isn't part of
the context that's actually interesting).
