John Howard 59ea134ce1 OCI Modifiers for Windows
Signed-off-by: John Howard <jhoward@microsoft.com>

Needed for the containerd work on Windows and integrating the
oci package from containerd into moby.

No longer sets defaults for
 - .Process.ConsoleSize
 - .Windows.IgnoreFlushesDuringBoot
 - .Windows.Network.AllowUnqualifiedDNSQuery

Adds helper functions and tests for
 - WithWindowsIgnoreFlushesDuringBoot
 - WithWindowNetworksAllowUnqualifiedDNSQuery

Updates `ctr run` on Windows to use the new helper functions,
ConsoleSize is already handled.
