Add type, size and (optional) cumulativesize to ipfs ls JSON output

Enhancement

Description:

Part of #3056 and #3081, we should consider adding a Type, Size and (optional, see #5804) CumulativeSize to the root node for ipfs ls output. This information (except perhaps the cumsize) should already be available when performing the ls and is quite useful for some purposes (i.e. ipfs-search.com), as it saves an additional call to ipfs files stat.

Perhaps it even makes sense to include the full stat output, for consistency?

Current output of ipfs ls --enc=json /ipfs/QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP:

{
  "Objects": [
    {
      "Hash": "/ipfs/QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP",
      "Links": [
        {
          "Name": "reindex",
          "Hash": "Qmac74sj9SgTVVVHFgWrFL6wyUQ8k8sgK4LYcEPTNoz3jW",
          "Size": 18132,
          "Type": 1
        }
      ]
    }
  ]
}

Output of ipfs files stat --enc=json /ipfs/QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP:

{
  "Hash": "QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP",
  "Size": 0,
  "CumulativeSize": 18187,
  "Blocks": 1,
  "Type": "directory"
}

Where we're coming from - ipfs file ls --enc=json:

{
  "Arguments": {
    "/ipfs/QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP": "QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP"
  },
  "Objects": {
    "QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP": {
      "Hash": "QmYcutogfHrrxigzVw2Vi8P1cdiuXNn9VecL9cy95wB9MP",
      "Size": 0,
      "Type": "Directory",
      "Links": [
        {
          "Name": "reindex",
          "Hash": "Qmac74sj9SgTVVVHFgWrFL6wyUQ8k8sgK4LYcEPTNoz3jW",
          "Size": 18132,
          "Type": "Directory"
        }
      ]
    }
  }
}

Type and Size seem to have been added by now, CumulativeSize is still lacking. Closing, for now, as CumSize has its own issue now.
