Currently a bunch of KVM specific interfaces are leaked into the vmm
crate which should ideally does not contain any hypervisor specific data
structures.

The IMSIC attr of RISC-V AIA is wrongly configured to start from 0, which
would error out with `os error 22` (invalid argument).
```console
Error booting VM: VmBoot(DeviceManager(CreateInterruptController(CreateAia(CreateVaia(Vaia error SetDeviceAttribute(SetDeviceAttribute(Invalid argument (os error 22))))))))
```
`riscv_imsic_attr_of` should shift `cpu_index` by 1 here to produce
correct IMSIC attr.

Currently, Cloud Hypervisor does not set a VIRTIO_IOMMU_F_INPUT_RANGE
feature bit for the VirtIO IOMMU device, which, according to spec[1],
means that the guest may use the whole 64-bit address space is for
IOMMU purposes:
>If the feature is not offered, virtual mappings span over the whole
>64-bit address space (start = 0, end = 0xffffffff ffffffff)
As far as I am aware, there are currently no host platforms on
the market capable of addressing the whole 64-bit address space.
For example, I am currently working with a host platform that reports
39-bit address space for IOMMU purposes:
>DMAR: Host address width 39
When running a VFIO pass-through guest on such a platform, NVIDIA
driver in guest gets DMA mapping failures when working with large data,
and this results in Cloud Hypervisor exiting with the following error:
>cloud-hypervisor: 1501.220535s: <__iommu>
>ERROR:virtio-devices/src/thread_helper.rs:53 -- Error running worker:
>HandleEvent(Failed to process request queue : ExternalMapping(Custom
>{ kind: Other, error: "failed to map memory for VFIO container, iova
>0x7fff00000000, gpa 0x24ce25000, size 0x1000: IommuDmaMap(Error(22))"
>}))
Passing "--platform iommu_address_width=39" to Cloud Hypervisor built
with this change fixes this.

When VM restore fails, the VMM state is left with some side-effects,
such as a VM being created. It would prevent the VMM from creating and
booting a new VM or restoring from a VM snapshot.
To fix this issue, this patch explicitly handles the side effects to the
VMM state when VM restore fails, e.g. clear the VmConfig and shutdown
the VM being created.
Fixes: #6869

With VM restore, the VMM is always re-creating a VM based on the
restored `VmConfig`. We should always re-generate the 'console_info'
from the `Vmm` struct to stay consistent with the new VM being created.
