c48e82915d vmm: Make kernel optional in VM internals
When booting with TDX no kernel is supplied as the TDFV is responsible
for loading the OS. The requirement to have the kernel is still
currently enforced at the validation entry point; this change merely
changes function prototypes and stored state to use Option<> to support.

56028fb214 Try to restore pty configuration on reboot
When a vm is created with a pty device, on reboot the pty fd (sub
only) will only be associated with the vmm through the epoll event
loop. The fd being polled will have been closed due to the vm itself
dropping the pty files (and potentially reopening the fd index to a
different item making things quite confusing) and new pty fds will be
opened but not polled on for input.

This change creates a structure to encapsulate the information about
the pty fd (main File, sub File and the path to the sub File). On
reboot, a copy of the console and serial pty structs is then passed
down to the new Vm  instance which will be used instead of creating a
new pty device.

This resolves the underlying issue from #2316.

933d41cf2f vmm: Provide DMA mapping handlers to virtio-mem devices
Now that virtio-mem devices can update VFIO mappings through dedicated
handlers, let's provide them from the DeviceManager.

Important to note these handlers should either be provided to virtio-mem
devices or to the unique virtio-iommu device. This must be mutually
exclusive.

61f9a4ec6c virtio-devices: mem: Accept handlers to update DMA mappings
Create two functions for registering/unregistering DMA mapping handlers,
each handler being associated with a VFIO device.

Whenever the plugged_size is modified (which means triggered by the
virtio-mem driver in the guest), the virtio-mem backend is responsible
for updating the DMA mappings related to every VFIO device through the
handler previously provided.

It's important to update the map when the handler is either registered
or unregistered as well, as we don't want to miss some plugged memory
that would have been added before the VFIO device is added to the VM.

080ea31813 pci, vmm: Manage VFIO DMA mapping from DeviceManager
Instead of letting the VfioPciDevice take the decision on how/when to
perform the DMA mapping/unmapping, we move this to the DeviceManager
instead.

The point is to let the DeviceManager choose which guest memory regions
should be mapped or not. In particular, we don't want the virtio-mem
region to be mapped/unmapped as it will be virtio-mem device
responsibility to do so.
