Add support for running container from OCI archive without requiring separate load command

[austinvazquez]

What is the problem you're trying to solve

I have a use case which is moving from podman to nerdctl/containerd which currently runs container image from OCI archive without requiring load as a separate step.

Describe the solution you'd like

I would like to provide a similar experience:

$ nerdctl run oci-archive:///path/to/oci/archive /bin/bash

Additional context
