It's not possible to provide the guest with the Security extensions

However, we weren't checking for this combination, with the result
that QEMU would assert if you tried it:
$ qemu-system-aarch64 -enable-kvm -machine virt,secure=on -cpu host -display
none
Unexpected error in object_property_find_err() at ../../qom/object.c:1304:
qemu-system-aarch64: Property 'host-arm-cpu.secure-memory' not found
Aborted
Check for this combination of options and report an error, in the
same way we already do for attempts to give a KVM or HVF guest the
Virtualization or MTE extensions. Now we will report:
qemu-system-aarch64: mach-virt: KVM does not support providing Security
extensions (TrustZone) to the guest CPU

Not a regression, so not worth fixing in 7.0.
