Add kvm_arch_vcpu_pre_fault_memory() for arm64. The implementation hands off the stage-2 faulting logic to either gmem_abort() or user_mem_abort().

Add an optional page_size output parameter to user_mem_abort() to return the VMA page size, which is needed when pre-faulting.

Update the documentation to clarify x86 specific behaviour.

It works quite well for a few cases I have, so FWIW
