This adds section to describe HW that should be passed through to the
VM. This enables Hardware-level isolation provided by XEN for
e.g. functional safety use cases.
Adds hwConfig object to the VM section which is apt to describe the
initial configuration for the VM, sush as number of vcpus and memory,
provided to the VM.
Hardware description includes path to the device-tree, that should be
passed to the VM and the hardware configuration parameters which
provides all needed data for VM to use the devices, such as:
- dtdevs: host device tree nodes to passthrough to the VM;
- iomems: allow auto-translated domains to access specific hardware
I/O memory pages;
- irqs: allows VM to access specific physical IRQs.

This adds a section to describe VM based container configurations to be
used by OCI runtimes using hardware virtualization to provide another
layer of isolation.
As part of this section we define 3 entries:
- A virtual machine root image opbject. This is the guest image that
contains the virtual machine root filesystem. The container image will
be mounted on top of that filesystem.
- A virtual machine kernel object. This is the kernel that will boot
inside the virtual machine. The object describes the host kernel image
path, additional parameters and an optional guest initrd for the
kernel to use.
- A virtual machine hypervisor object. This is the hypervisor that will
manage the container virtual machine from the host. The object
describe a hypervisor binary path and some additional parameters.
