vmm: tdx: Pass ACPI tables through the HOB

vmm: acpi: Create ACPI tables for TDX
The way to create ACPI tables for TDX is different as each table must be passed through the HOB. This means the XSDT table is not required since the firmware will take care of creating it. Same for RSDP, this is firmware responsibility to provide it to the guest. That's why this patch creates a TDX dedicated function, returning a list of Sdt objects, which will let the calling code copy the content of each table through the HOB.

vmm: tdx: Only create ACPI tables if not running TDX
In case of TDX, we don't want to create the ACPI tables the same way we do for all the other use cases. That's because the ACPI tables don't need to be written to guest memory at a specific address, instead they are passed directly through the HOB.

vmm: Send FDs across unix socket for migration when in local mode
When in local migration mode send the FDs for the guest memory over the socket along with the slot that the FD is associated with.

`tap` has its default value set to `None`, but in the openapi yaml file we've been setting it to `""`. When using this code on the Kata Containers side we'd be hit by a non expected behaviour of cloud-hypervisor, as even when using a different method to initialise the `tuntap` device the code would be treated as if using `--net tap` (which is a valid use-case).
