HWPOISON: Add page flag for poisoned pages
Hardware poisoned pages need special handling in the VM and shouldn't be
touched again. This requires a new page flag. Define it here.
The page flags wars seem to be over, so it shouldn't be a problem
to get a new one.
v2: Add TestSetHWPoison (suggested by Johannes Weiner)
