On AArch64, device hotplug can be enabled with ACPI. Therefore,
this commit enables the hotplug test case for following devices:
- PCI bar reprogramming
- virtio-disk
- virtio-net
- macvtap
- virtio-vsock
- virtio-pmem: Works with the latest reference kernel
- virtio-fs: Works with the latest reference kernel

Currently vfio and nested virtualization is not used on AArch64,
and SGX is a x86_64 only feature. Therefore this commit adds the
architecture gates for helper functions related to vfio, SGX, and
nested virtualization to mute warnings when building tests on the
AArch64 platform.

Memory hotplug and virtio_balloon works on arm64 with:
- memory hotplug: An updated kernel using ACPI
- virtio balloon: `stress` installed in the cloud image
Therefore, we can enable test cases for them in integration test.

For AArch64, now virtual IOMMU is only tested on FDT, not ACPI.
In the case of FDT, the behavior of IOMMU is a bit different with ACPI.
All the devices on the PCI bus will be attached to the virtual IOMMU,
except the virtio-iommu device itself. So these devices will all be
added to IOMMU groups, and appear in folder '/sys/kernel/iommu_groups/'.
The result is, on AArch64 IOMMU group '0' contains "0000:00:01.0" which
is the console device. But on X86, console device is not attached to
IOMMU. So the IOMMU group '0' contains "0000:00:02.0" which is the first
disk.

This patch adds a separate function to launch two guest VMs and ensure
they are connected through ovs-dpdk, so that we can reuse this function

Currently we need to test both device tree and ACPI on AArch64. As
the number of ACPI test cases is gradually increasing and expected
to increase in the future, it is better to extract all ACPI test
cases on AArch64 to a single module.

This test exercises the local live-migration between two Cloud
Hypervisor VMs on the same host. It ensures the following behaviors:
1. The source VM is up and functional (including various virtio-devices
are working properly);
2. The 'send-migration' and 'receive-migration' command finished
successfully;
3. The source VM terminated gracefully after live migration;
4. The destination VM is functional (including various virtio-devices
are working properly) after live migration.
Note: This test does not use vsock as we can't create two identical
vsock on the same host.

AArch64 tests were divided into 2 steps:
- Build and test with 'acpi' feature
- Build and test without 'acpi'
This can be optimized. We need only to build and test once with default
features ('acpi' is enabled).
On AArch64, ACPI only works with UEFI. If UEFI is not available, guest
kernel fall back to use FDT. Most AArch64 test cases boot from direct
kernel, the guest will keep using FDT even if ACPI is enabled. So
nothing is broken.

The virtio_balloon test is a bit flaky since we can't really know how
much the balloon is gonna be deflated when the guest is under memory
pressure. That's why it's safer to simply check that the balloon is not
the initial size anymore.
One small detail, but we don't need to check for the balloon size to be
higher than 0 since the returned value is a u64.

The new test_virtio_balloon() is to verify if the 'deflate_on_oom'
parameter works. Its testing result is as follows:
1. Start a 4G guest with 2G balloon, check memory once starts up.
total_mem is 4294967296 bytes
actual_mem is 2147483648 bytes
orig_balloon is 2147483648 bytes
total used free shared buff/cache available
Mem: 3.8Gi 2.1Gi 1.6Gi 0.0Ki 140Mi 1.6Gi
Swap: 0B 0B 0B
2. Run a command in guest to eat up 25G memory, and check again.
total_mem is 4294967296 bytes
actual_mem is 3121610752 bytes
deflated_balloon is 1173356544 bytes
total used free shared buff/cache available
Mem: 3.8Gi 1.2Gi 2.6Gi 0.0Ki 49Mi 2.5Gi
Swap: 0B 0B 0B
From above, we can notice the balloon memory indeed deflates from
2147483648 bytes to 1173356544 bytes once an oom is going to be
triggered.
