Add a no-op stub for kvm_arch_gmem_invalidate if
CONFIG_HAVE_KVM_ARCH_GMEM_INVALIDATE=n. This allows defining
kvm_gmem_free_folio without ifdef-ery, which allows more cleanly using
guest_memfd's free_folio callback for non-arch-invalidation related
code.

We'll now always perform a callback from the core, but I guess that's tolerable.
