With the introduction of Windows Server 2022, some images have been updated
to support WS2022 in their manifest list. This commit updates the test images
accordingly.

CRI container runtimes mount devices (set via kubernetes device plugins)
to containers by taking the host user/group IDs (uid/gid) to the
corresponding container device.
This triggers a problem when trying to run those containers with
non-zero (root uid/gid = 0) uid/gid set via runAsUser/runAsGroup:
the container process has no permission to use the device even when
its gid is permissive to non-root users because the container user
does not belong to that group.
It is possible to workaround the problem by manually adding the device
gid(s) to supplementalGroups. However, this is also problematic because
the device gid(s) may have different values depending on the workers'
distro/version in the cluster.
This patch suggests to take RunAsUser/RunAsGroup set via SecurityContext
as the device UID/GID, respectively. The feature must be enabled by
setting device_ownership_from_security_context runtime config value to
true (valid on Linux only).

There was recent changes to cri to bring in a Windows section containing a
security context object to the pod config. Before this there was no way to specify
a user for the pod sandbox container to run as. In addition, the security context
is a field for field mirror of the Windows container version of it, so add the
ability to specify a GMSA credential spec for the pod sandbox container as well.

Exclude the `security.selinux` xattr when copying content from layer
storage for image volumes. This allows for the already correct label
at the target location to be applied to the copied content, thus
enabling containers to write to volumes that they implicitly expect to be
able to write to.

Remove build tags which are already implied by the name of the file.

Before this change, for several of the services that `WithServices`
handles, only the grpc client is supported.
Now, for instance, one can use an `images.Store` directly instead of
only an `imagesapi.StoreSlient`.
Some of the methods have been renamed to satisfy the difference between
using a grpc `<Foo>Client` vs the main interface.
I did not see a good candidate for TaskService so have left that mostly
unchanged.

CNI plugins that need to wait for network state to converge
may want to cancel waiting when a short lived pod is deleted.
However, there is a race between when kubelet asks the runtime
to create the sandbox for the pod, and when the plugin is able
request the pod object from the apiserver. It may be the case
that the plugin receives the new pod, rather than the pod
the sandbox request was initiated for.
Passing the pod UID to the plugin allows the plugin to check
whether the pod it gets from the apiserver is actually the
pod its sandbox request was started for.

Similar to other deferred cleanup operations, teardownPodNetwork should
use a different context as the original context may have expired,
otherwise CNI wouldn't been invoked, leading to leak of network
resources, e.g. IP addresses.

This commit adds support for the PID namespace mode TARGET
when generating a container spec.
The container that is created will be sharing its PID namespace
with the target container that was specified by ID in the namespace
options.

Looks like we had our own copy of the "getDevices" code already, so use
that code (which also matches the code that's used to _generate_ the spec,
so a better match).
Moving the code to a separate file, I also noticed that the _unix and _linux
code was _exactly_ the same (baring some `//nolint:` comments), so also
removing the duplicated code.
With this patch applied, we removed the dependency on the libcontainer/devices
package (leaving only libcontainer/user).

Move `pkg/cri/opts.WithoutRunMount` function to `oci.WithoutRunMount`
so that it can be used without dependency on CRI.
Also add `oci.WithoutMounts(dests ...string)` for generality.
