f4495de143 vmm: Improve handling of shared memory backing 
As huge pages are always MAP_SHARED then where the shared memory would
be checked (for vhost-user and local migration) we can also check
instead for huge pages.

The checking is also extended to cover the memory zones based
configuration as well.

99d9a3d299 vmm: memory_manager: Avoid MAP_PRIVATE CoW with VFIO for hugepages too 
We can't use MAP_ANONYMOUS and still have huge pages so MAP_SHARED is
effectively required when using huge pages.

Unfortunately it is not as simple as always forcing MAP_SHARED if
hugepages is on as this might be inappropriate in the backing file case
hence why there is additional complexity of assigning to mmap_flags on
each case and the MAP_SHARED is only turned on for the anonymous file
huge page case as well as anonymous shared file case.

See: #4805

df7c728399 vmm: memory_manager: Only file back memory when required

As a side effect this addresses an issue with CoW (mmap with MAP_PRIVATE
but no MAP_ANONYMOUS) when the memory is pinned for VFIO.

cb171d4a23 device_manager: Avoid checking io_uring support when it's not needed 
After testing, io_uring_is_supported() causes about 38ms of
overhead when creating virtio-blk. By modifying the position
of io_uring_is_supported(), the overhead of creating virtio-blk
is reduced to less than 1ms when we close io_uring.

1f0e5eb66a vmm: virtio-devices: Restore every VirtioDevice upon creation 
Following the new design proposal to improve the restore codepath when
migrating a VM, all virtio devices are supplied with an optional state
they can use to restore from. The restore() implementation every device
was providing has been removed in order to prevent from going through
the restoration twice.

Here is the list of devices now following the new restore design:

- Block (virtio-block)
- Net (virtio-net)
- Rng (virtio-rng)
- Fs (vhost-user-fs)
- Blk (vhost-user-block)
- Net (vhost-user-net)
- Pmem (virtio-pmem)
- Vsock (virtio-vsock)
- Mem (virtio-mem)
- Balloon (virtio-balloon)
- Watchdog (virtio-watchdog)
- Vdpa (vDPA)
- Console (virtio-console)
- Iommu (virtio-iommu)

b4e3942708 api: Fix vm.add-device argument type 
The add_device() function, from the device manager code, takes a
DeviceConfig as a parameter, instead of a VmAddDevice.

The change was originally done as part of 34412c9b41 and it didn't
break Kata Containers because the VmAddDevice and DeviceConfig structs
share most of their fields, besides the optional for serialization
`pci_segment`, which is not used by the client yet.
