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.

Windows systems are capable of running both Windows Containers and Linux
containers. For windows containers we need to sanitize the volume path
and skip non-C volumes from the copy existing contents code path. Linux
containers running on Windows and Linux must not have the path sanitized
in any way.
Supplying the targetOS of the container allows us to proprely decide
when to activate that code path.
