virtio,pc,pci: bug fixes, new test

Some small bug fixes, notably a fix for a regression
in cpu hotplug after migration. I also included a
new test, just to help make sure we don't regress cxl.

Revert "hw/acpi: Make CPUs ACPI `presence` conditional during vCPU hot-unplug"

This reverts commit 2d6cfbaf174b91dfa9a50065f7494634afb39c23.

The patch is supposed to be part of ARM CPU hotplug series and has not value
on its own without it. The series however is still in RFC stage and outside
of scope 9.2 release.

On top of that it introduces not needed callback that pokes directly into
CPU state without any need for that. Instead properties and AML generator
option should be used to configure static platform depended vCPU presence
state.

Drop the patch so that corrected version could be posted along with
ARM CPU hotplug series and properly reviewed in relevant context.
That also helps us to keep history cleaner with new patch being
against original code vs a string of fixups on top of current mess.

hw/acpi: Update ACPI `_STA` method with QOM vCPU ACPI Hotplug states

Reflect the QOM vCPUs ACPI CPU hotplug states in the `_STA.Present` and
and `_STA.Enabled` bits when the guest kernel evaluates the ACPI
`_STA` method during initialization, as well as when vCPUs are
hot-plugged or hot-unplugged. If the CPU is present then the its
`enabled` status can be fetched using architecture-specific code [1].

`enabled status

hw/acpi: Make CPUs ACPI `presence` conditional during vCPU hot-unplug

On most architectures, during vCPU hot-plug and hot-unplug actions, the
firmware or VMM/QEMU can update the OS on vCPU status by toggling the
ACPI method `_STA.Present` bit. However, certain CPU architectures
prohibit [1] modifications to a CPU’s `presence` status after the kernel
has booted.

This limitation [2][3] exists because many per-CPU components, such as
interrupt controllers and various per-CPU features tightly integrated
with CPUs, may not support reconfiguration once the kernel is
initialized. Often, these components cannot be powered down, as they may
belong to an `always-on` power domain. As a result, some architectures
require all CPUs to remain `_STA.Present` after system initialization.

Therefore, it is essential to mirror the exact QOM vCPU status through
ACPI for the Guest kernel. For this, we should determine—via
architecture-specific code[4]—whether vCPUs must always remain present
and whether the associated `AcpiCpuStatus::cpu` object should remain
valid, even following a vCPU hot-unplug operation.

hw/acpi: Update CPUs AML with cpu-(ctrl)dev change

CPUs Control device(\\_SB.PCI0) register interface for the x86 arch is IO port
based and existing CPUs AML code assumes _CRS objects would evaluate to a system
resource which describes IO Port address. But on ARM arch CPUs control
device(\\_SB.PRES) register interface is memory-mapped hence _CRS object should
evaluate to system resource which describes memory-mapped base address. Update
build CPUs AML function to accept both IO/MEMORY region spaces and accordingly
update the _CRS object.

hw/acpi/cpu: Have build_cpus_aml() take a build_madt_cpu_fn callback

build_cpus_aml() is architecture independent but needs to create architecture-
specific CPU AML. So far this was achieved by using a virtual method from
TYPE_ACPI_DEVICE_IF. However, build_cpus_aml() would resolve this interface from
global (!) state. This makes it quite incomprehensible where this interface
comes from (TYPE_PIIX4_PM?, TYPE_ICH9_LPC_DEVICE?, TYPE_ACPI_GED_X86?) an can
lead to crashes when the generic code is ported to new architectures.

So far, build_cpus_aml() is only called in architecture-specific code -- and
only in x86. We can therefore simply pass pc_madt_cpu_entry() as callback to
build_cpus_aml(). This is the same callback that would be used through
TYPE_ACPI_DEVICE_IF.

qapi acpi: Elide redundant has_FOO in generated C

The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with. Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step. This is the step for qapi/acpi.py.

Said commit explains the transformation in more detail. The invariant
violations mentioned there do not occur here.

Remove unnecessary minimum_version_id_old fields

The migration code will not look at a VMStateDescription's
minimum_version_id_old field unless that VMSD has set the
load_state_old field to something non-NULL. (The purpose of
minimum_version_id_old is to specify what migration version is needed
for the code in the function pointed to by load_state_old to be able
to handle it on incoming migration.)

We have exactly one VMSD which still has a load_state_old,
in the PPC CPU; every other VMSD which sets minimum_version_id_old
is doing so unnecessarily. Delete all the unnecessary ones.

Commit created with:
sed -i '/\.minimum_version_id_old/d' $(git grep -l '\.minimum_version_id_old')
with the one legitimate use then hand-edited back in.
