75b9e70ec8 virtio-devices: Set AccessPlatform trait through VirtioDevice 
Add a new method set_access_platform() to the VirtioDevice trait in
order to allow an AccessPlatform trait to be setup on any virtio device.

f29f3085ed virtio-queue: Remove queue addresses translation 
Now that the virtio-devices crate can take care of the queue addresses
when placed behind a vIOMMU, we can remove the corresponding code.

ce6446501d virtio-devices: Handle queue addresses translation 
Upon the enablement of the queue by the guest, we perform a translation
of the descriptor table, the available ring and used ring addresses
prior to enabling the device itself. This only applies to the case where
the device is placed behind a vIOMMU, which is the reason why the
translation is needed. Indeed, the addresses allocated by the guest are
IOVAs which must be translated into GPAs before we can access the queue.

de3e003e3e virtio-devices: Handle virtio queues interrupts from transport layer 
Instead of relying on the virtio-queue crate to store the information
about the MSI-X vectors for each queue, we handle this directly from the
PCI transport layer.

This is the first step in getting closer to the upstream version of
virtio-queue so that we can eventually move fully to the upstream
version.

53caa565bb virtio-devices: Add openat() syscall to seccomp filter 
When freeing memory sometimes glibc will attempt to read
"/proc/sys/vm/overcommit_memory" to find out how it should release the
blocks. This happens sporadically with Cloud Hypervisor but has been
seen in use. It is not necessary to add the read() syscall to the list
as it is already included in the virtio devices common set. Similarly
the vCPU and vmm threads already have both these in the allowed list.

Fixes: #3609

7b9a110540 vmm: tdx: Pass ACPI tables through the HOB 
Relying on helpers for creating the ACPI tables and to add each table to
the HOB, this patch connects the dot to provide the set of ACPI tables
to the TD firmware.

2acb50f752 arch: x86_64: tdx: Add ACPI table helper to TdHob 
Adding a new method to the TdHob structure so that we can easily insert
a ACPI_TABLE_HOB into the HOB.

ea0729c016 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.

cdc14815be 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.

4fda4ad6c9 arch, vmm: tdx: Remove TD_VMM_DATA mechanism 
It's been decided the ACPI tables will be passed to the firmware in a
different way, rather than using TD_VMM_DATA. Since TD_VMM_DATA was
introduced for this purpose, there's no reason to keep it in our
codebase.

eb5c5f2c7f tests: Add integration test for O_DIRECT 
Both OVMF and RHF firmwares triggered an error when O_DIRECT was used
because they didn't align the buffers to the block sector size.

In order to prevent regressions, we're adding a new test validating the
VM can properly boot when the OS disk is opened with O_DIRECT and booted
from the rust-hypervisor-fw.
