virtio: replace restricted mem access flag with callback
Instead of having a global flag to require restricted memory access
for all virtio devices, introduce a callback which can select that
requirement on a per-device basis.
For convenience add a common function returning always true, which can
be used for use cases like SEV.
Per default use a callback always returning false.
As the callback needs to be set in early init code already, add a
virtio anchor which is builtin in case virtio is enabled.
