Support State.Error field in inspect command

[ningziwen]

What is the problem you're trying to solve

nerdctl inspect cannot return State.Error field today.

$ nerdctl run -d public.ecr.aws/amazonlinux/amazonlinux:2
2fd4c9d197320279055bfca5a109433935e762fc91bcbe371815a6cf7f39fe03
$ nerdctl inspect --format {{.State.Status}}:{{.State.Error}} 2fd4c9d197320279055bfca5a109433935e762fc91bcbe371815a6cf7f39fe03
WARN[0000] failed to inspect NetNS                       error="failed to Statfs \"/proc/4058/ns/net\": no such file or directory" id=2fd4c9d197320279055bfca5a109433935e762fc91bcbe371815a6cf7f39fe03
FATA[0000] 1 errors: [template parsing error: template: :1:26: executing "" at <.State.Error>: map has no entry for key "Error"]

Describe the solution you'd like

State.Error exists in the inspect response, and it is an existing TODO in comment.

nerdctl/pkg/inspecttypes/dockercompat/dockercompat.go

Line 170 in e09d7f8

// TODO: Error string

container exit error is rendered when the container process exit :
https://github.com/containerd/containerd/blob/v1.6.19/process.go#L44

we need to store it in container metadata so we can retrieve it later

I will take this ticket :)
