Bo Chen fe5f991c37 vmm: Support device passthrough with vfio cdev and iommufd ...

When `--platform iommufd=on` is set, use the vfio cdev interface backed
by iommufd instead of the legacy vfio container/group interface for
device passthrough.

The cdev path opens '/dev/iommu' via IommuFd, allocates an IOAS, and
binds VFIO devices through VfioIommufd. The legacy container/group path
remains the default and is used when iommufd is not enabled.

Add iommufd-ioctls as a workspace dependency and enable the "vfio_cdev"
feature on vfio-ioctls for KVM builds.

Fixes: #6892
