In order to support nested virtualization and nested device passthrough
from our CI tests, we need some extra kernel configuration options to be
enabled.
CONFIG_KVM and CONFIG_VIRTUALIZATION for nested virtualization.
CONFIG_VFIO for nested device passthrough.
CONFIG_VIRTIO_IOMMU and CONFIG_ACPI_IORT for virtio-iommu support.
With all these new options applied, we can leverage virtio-iommu to
attach some VFIO devices to it and pass them through a second layer of
virtualization.

The existing integration tests are extended to support both use cases
where dax=on and dax=off.
In order to support DAX, the kernel configuration needs to be updated to
include CONFIG_FS_DAX and CONFIG_ZONE_DEVICE.

The last kernel we were using included some manual porting of the
virtio-pmem and virtio-fs patches. By moving to 5.3-rc3, we are now
closer to upstream since the virtio-pmem patches are part of the linux
kernel now. Additionally, this includes the latest patches from
virtio-fs maintainers, which works with the latest version of virtiofsd.

This commit introduces the testing of the --fs option based on the
virtio-fs implementation. This does not simply add a test, but also
updates the integration script by generating a new kernel embedding
the virtio-fs patches and by downloading the virtiofsd daemon.

Remove some of the kernel configuration options that are not necessary
for manual testing and for testing with the CI in order to reduce the
kernel build time.

This is helpful and actually needed to ensure everyone is testing
from the same kernel reference.
