specgen,run: support running container from valid manifest list

Following PR adds support for running containers from a manifest list
present on localstorage. Before this PR podman only supports running
containers from valid images but not from manifest list.

So `podman run -it --platform <some> <manifest-list> command` should
become functional now and users should be able to resolve images on the
bases of provided `--platform` string.

Example
```
podman manifest create test
podman build --platform linux/amd64,linux/arm64 --manifest test .
podman run --rm --platform linux/arm64/v8 test uname -a
```

Closes: https://github.com/containers/podman/issues/14773
