Printdesks command

[WhySoBad]

Hi

I've added the hyprctl printdesks command which outputs information about all vdesks currently available

The output below is an example of running hyprctl printdesks -j which can be easily processed by other applications (e.g. sidebar widgets):

[
  {
    "id": 4,
    "name": "4",
    "focused": false,
    "populated": false
  },
  {
    "id": 3,
    "name": "3",
    "focused": false,
    "populated": false
  },
  {
    "id": 2,
    "name": "2",
    "focused": false,
    "populated": true
  },
  {
    "id": 1,
    "name": "1",
    "focused": true,
    "populated": true
  }
]

Now, the plugin stores a list with all open windows for every vdesk which has to be updated when a window opens, closes or gets moved to another workspace (which potentially is part of another vdesk). Therefore, it was necessary to add some event listeners.

The branch is rebased onto dev and therefore the new feature will be available for all users as soon as the next hyprland version is released.

Thank you very much for your efforts and contribution.
Your implementation, unfortunately, adds a lot of overhead, listeners and new code that imo is not necessary.

As mentioned in one of the review comments, all this can be achieved without adding new structures, by simply iterating over the vdesks. Please, correct me if I'm wrong here.

Just to be clear, I'm not against implementing this functionality, it's just that your proposition adds too much complexity :)

I'd merge this pull request as a squash merge since the pull request contains some commits which were updated the last commit
