Add support for grouping root workspace folders

[mcm-ham]

I'd like to nest workspace folders like this:

"folders": [
  {
    "name": "e2e",
    "folders": [
      {
        "name": "app1",
        "path": ""
      },
      {
        "name": "app2",
        ""
      }
    ]
  }
],

Functionally the folders can act the same as if the list were flat, but just in UI the nested structure is shown. My immediate need would also be solved by #32693 but I've used this feature a bit in Visual Studio to group shared library projects where for other reasons the folder structure on disk needed to be different.

Is this #76904 ?
