This commit adds `VmExit::Debug` for x86/KVM. When the guest hits a
hardware breakpoint, `VcpuExit::Debug` vm exit occurs. This vm exit
will be handled with code implemented in the following commits.

This commit adds `set_guest_debug` implementation for x86/KVM. This
function sets hardware breakpoints and single step to debug registers.
NOTE: The `set_guest_debug` implementation is based on the crosvm
implementation [1].

This commit adds `translate_gva` for x86/KVM. The same name function is
already implemented for MSHV, but the implementation differs as
KVM_TRANSLATE does not take the flag argument and does not return status
code. This change requires the newer version of kvm-ioctls [1].

`translate_gva` returns mshv-specific type `hv_translate_gva_result`.
This return type is not a problem since this function is implemented
only for mshv, but we need to remove the type as the same function will
be implemented for KVM in PR #3575. This commit replaces the
mshv-specific type with `u32`.

I incorrectly used the MSI message control register values for the mask
not the the MSI-X control registers.
The correct writable fields for MSI-X are only bits 14 and 15 of 2nd
16-bit word.
Those are:
* Function Mask: 14
* MSI-X Enable: 15
See "Table 7-47 Message Control Register for MSI-X" from
"NCB-PCI_Express_Base_5.0r1.0-2019-05-22.pdf"

42b5d4a2f7 has changed how the PciBdf
field of a DeviceNode is represented (from an int32 to its own struct).
To avoid marshelling / demarshelling issues for the projects relying on
the openapi auto generated code, let's propagate the change, updating
the yaml file accordingly.

`Dies per package` setting of VCPU topology doesnot apply on AArch64.
Now we only accept `1` value. This way we can make the `dies` field
transparent, avoid it from impacting the topology setting.

The logic of determining VCPU index in creating `cpu-map` node of FDT

If `--local` is provided or if the version is not available then build
the container before use. This allows combining updates to the
Dockerfile with a full CI run.
Drop the "--dev" parameter as we only support one container type for
simplicity.

For vhost-user devices, we don't want to loose the vhost-user protocol
feature through the negotiation between guest and device. Since we know
VIRTIO has no knowledge of the vhost-user protocol feature, there is no
way it would ever be acknowledged by the guest. For that reason, we
create each vhost-user device with the set of acked features containing
the vhost-user protocol feature is this one was part of the available
list.
Having the set of acked features containing this bit allows for solving
a bug that was happening through the migration process since the
vhost-user protocol feature wasn't explicitely enabled.

Based on the helpers from the hypervisor crate, the VMM can identify
what type of hypercall has been issued through the KVM_EXIT_TDX reason.
For now, we only log warnings and set the status to INVALID_OPERAND
since these hypercalls aren't supported. The proper handling will be
implemented later.

Relying on the recent additions to the kvm-ioctls crate, this commit
implements the support for providing the exit reason details to the
caller, which allows the identification of the type of hypercall that
was issued. It also introduces a way for the consumer to set the status
code that must be sent back to the guest.
