HWPOISON: Add simple debugfs interface to inject hwpoison on arbitary PFNs

Useful for some testing scenarios, although specific testing is often
done better through MADV_POISON

This can be done with the x86 level MCE injector too, but this interface
allows it to do independently from low level x86 changes.

v2: Add module license (Haicheng Li)
