Implement KVM_PRE_FAULT_MEMORY on s390, and update documentation and
selftests accordingly.
Faulted-in pages will be marked as accessed, unlike x86, otherwise they
will trigger a minor fault when accessed. Avoiding such faults is one of
the points of KVM_PRE_FAULT_MEMORY.
CCing x86 people due to changes in the documentation and the selftests
