machine: allow early use of machine_require_guest_memfd
Ask the ConfidentialGuestSupport object whether to use guest_memfd for KVM-backend private memory. This bool can be set in instance_init (or user_complete) so that it is available when the machine is created. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
