linux: Add keyboard shortcuts for menus (#22074)

Browse source 
Closes #19837

This PR is a continuation of [linux: Implement
Menus](https://github.com/zed-industries/zed/pull/21873) and should only
be reviewed once the existing PR is merged.

I created this as a separate PR as the existing PR was already reviewed
but is yet to merge, and also it was my initial plan to do it in
separate parts because of the scope of it. This will also help reviewing
code faster.

This PR adds two new types of keyboard shortcuts to make menu navigation
easier:

1. `Alt + Z` for Zed, `Alt + F` for File, `Alt + S` for Selection, and
so on to open a specific menu with this combination. This mimics VSCode
and IntelliJ.

2. `Arrow Left/Right` when any menu is open. This will trigger the
current menu to close, and the previous/next to open respectively. First
and last element cycling is handled.

`Arrow Up/Down` to navigate menu entries is already there in existing
work.

Release Notes:

- Added keyboard navigation for menus on Linux (left/right). If you wish
to open menus with keyboard shortcuts add the following to your user
keymap:
    ```json
      {
        "context": "Workspace",
        "bindings": {
          "alt-z": ["app_menu::OpenApplicationMenu", "Zed"],
          "alt-f": ["app_menu::OpenApplicationMenu", "File"],
          "alt-e": ["app_menu::OpenApplicationMenu", "Edit"],
          "alt-s": ["app_menu::OpenApplicationMenu", "Selection"],
          "alt-v": ["app_menu::OpenApplicationMenu", "View"],
          "alt-g": ["app_menu::OpenApplicationMenu", "Go"],
          "alt-w": ["app_menu::OpenApplicationMenu", "Window"],
          "alt-h": ["app_menu::OpenApplicationMenu", "Help"]
        }
      }
    ```
