Plumb CRI Devices through to OCI WindowsDevices

There's two mappings of hostpath to IDType and ID in the wild:
- dockershim and dockerd-cri (implicitly via docker) use class/ID
-- The only supported IDType in Docker is 'class'.
-- https://github.com/aarnaud/k8s-directx-device-plugin generates this form
- https://github.com/jterry75/cri (windows_port branch) uses IDType://ID
-- hcsshim's CRI test suite generates this form

`://` is much more easily distinguishable, so I've gone with that one as
the generic separator, with `class/` as a special-case.
