This change adds support for CDI devices to the ctr --device flag.
If a fully-qualified CDI device name is specified, this is injected
into the OCI specification before creating the container.
Note that the CDI specifications and the devices that they represent
are local and mirror the behaviour of linux devices in the ctr command.

Several bits of code unmarshal image config JSON into an `ocispec.Image`, and then immediately create an `ocispec.Platform` out of it, but then discard the original image *and* miss several potential platform fields (most notably, `variant`).
Because `ocispec.Platform` is a strict subset of `ocispec.Image`, most of these can be updated to simply unmarshal the image config directly to `ocispec.Platform` instead, which allows these additional fields to be picked up appropriately.
We can use `tianon/raspbian` as a concrete reproducer to demonstrate.
Before:
```console
$ ctr content fetch docker.io/tianon/raspbian:bullseye-slim
...
$ ctr image ls
REF TYPE DIGEST SIZE PLATFORMS LABELS
docker.io/tianon/raspbian:bullseye-slim application/vnd.docker.distribution.manifest.v2+json sha256:66e96f8af40691b335acc54e5f69711584ef7f926597b339e7d12ab90cc394ce 28.6 MiB linux/arm/v7 -
```
(Note that the `PLATFORMS` column lists `linux/arm/v7` -- the image itself is actually `linux/arm/v6`, but one of these bits of code leads to only `linux/arm` being extracted from the image config, which `platforms.Normalize` then updates to an explicit `v7`.)
After:
```console
$ ctr image ls
REF TYPE DIGEST SIZE PLATFORMS LABELS
docker.io/tianon/raspbian:bullseye-slim application/vnd.docker.distribution.manifest.v2+json sha256:66e96f8af40691b335acc54e5f69711584ef7f926597b339e7d12ab90cc394ce 28.6 MiB linux/arm/v6 -
```

This flag allows cpuset.mems to be specified when running a container. If
provided, the container will use only the defined memory nodes.

If this command is used without "-Container:$false" and the "containerd" directory does not already exist all files will be merged into a single "containerd" file instead of a new directory.

This patch switches the Azure-based Windows workflows to using the
vanilla `2019-Datacenter` Azure SKU following the deprecation of the
old specialized `2019-Datacenter-with-Containers-smalldisk` SKU which
was previously used.

This commit fixes a broken link. This commit also updates the description about
the image handler. It now mentions about
`github.com/containerd/containerd/pkg/snapshotters` package.

To further some ongoing work in containerd to make as much code as possible
able to be used on any platform (to handle runtimes that can virtualize/emulate
a variety of different OSes), this change makes stats able to be handled on
any of the supported stat types (just linux and windows). To accomplish this,
we use the platform the sandbox returns from its `Platform` rpc to decide
what format the containers in a given sandbox are returning metrics in, then
we can typecast/marshal accordingly.
