zellij/commands: Prevent recursive sessions (#1766 )

* zellij/commands: Prevent recursive sessions

with session names specified in layout files. A "recursive session" is
created when, while running inside some zellij session, a user attempts
to spawn zellij and make it attach to that same session.

When attaching via CLI (`zellij attach`) we explicitly check for this
condition and error out when needed.

However, besides `zellij attach` it is also possible to declare the
session to attach to in layout files like so:

```yaml
session:
  name: "foo"
```

This takes a different codepath when starting zellij, and hence bypases
the checks we already have in place to avoid recursive sessions. Hence,
we implement the check in the other codepath, too, and prevent recursive
sessions from happening for good.

Fixes: #1735

This feature is gated behind the unstable feature flag. Because the serialization format will be changed at some point. We would still already be glad about early feedback on this feature.

Can be invoked through zellij action [ACTIONS].

Automatically sends the action to the current session, or if there is just one to the single session, if there are multiple sessions, then the session name must be specified.

Example:
```
zellij
zellij action NewTab:
```
Send actions to a specific session:
```
zellij -s fluffy-cat
zellij -s fluffy-cat action 'NewPane: , WriteChars: "echo Purrr\n"'
```
Open htop in a new tab:
```
zj action "NewTab: {run: {command: {cmd: htop}}}"
```

Fix: handling and overwriting options through the cli (https://github.com/zellij-org/zellij/pull/859)

THIS IS A BREAKING CHANGE: Previously it was only possible to turn off certain features through the cli, now it also is possible to overwrite this behavior - for that the following changed:
- renamed and inverted:
```
disable_mouse_mode -> mouse_mode
no_pane_frames -> pane_frames
```
- cli options added:
```
mouse-mode [bool]
pane-frames [bool]
simplified-ui [bool]
```
- cli flag removed:
```
simplified-ui
```
Now the cli options can optionally be toggled on, even if the config turns it off, example:
```
zellij options --mouse-mode true
```

Terminal compatibility: properly handle cursor shape changes in eg. Neovim (https://github.com/zellij-org/zellij/pull/659)
The resize and layout systems have been overhauled (https://github.com/zellij-org/zellij/pull/568)
- Resizing a terminal then returning it to its original size will now always return panes to their original sizes and positions
- Resize mode resizes panes by 5% of the space on screen, not some fixed number
- Panes on-screen keep their ratios – a screen split 50/50 between two panes will remain 50/50 even as the terminal is resized (https://github.com/zellij-org/zellij/issues/406)
- The terminal can now be resized without leaving fullscreen mode
- Layout parts are split into equal percentages if no explicit split-size is given (https://github.com/zellij-org/zellij/issues/619)
- Fixed display of the tab bar at small terminal widths

Add tabs to layouts (https://github.com/zellij-org/zellij/pull/625)

The layout has now a template, and tabs section. The template specifies the location a tab is inserted in with body: true.

Eg:

---
template:
  direction: Horizontal
  parts:
    - direction: Vertical
      borderless: true
      split_size:
        Fixed: 1
      run:
        plugin: tab-bar
    - direction: Vertical # <= The location of
      body: true          # <= the inserted tab.
    - direction: Vertical
      borderless: true
      split_size:
        Fixed: 2
      run:
        plugin: status-bar
tabs:
  - direction: Vertical # <= Multiple tabs can be
  - direction: Vertical # <= specified in the layout.
  - direction: Vertical

The NewTab action can optionally be bound to open a layout that is assumed to be in the new tabs section

This is a BREAKING CHANGE for people that have the NewTab action already bound in the config file:

- action: [NewTab, ]
  key: [F: 5,]

must now be specified as:

- action: [NewTab: ,]
  key: [F: 5,]

Optionally a layout that should be opened on the new tab can be specified:

- action: [NewTab: {
  direction: Vertical,
  parts: [ {direction: Horizontal, split_size: {Percent: 50}},
  {direction: Horizontal, run: {command: {cmd: "htop"}}},],
  key: [F: 6,]
