Command menu refactoring (#9257)

Refactored the `CommandMenu` component to make it more readable and
easier to refactor.
The file was way too big so I introduced a few hooks and eliminated code
duplication.

Introduced:
- `useMatchCommands` hook to match commands with the search
- `useCommandMenuCommands` which returns all command menu commands
- `useMatchingCommandMenuCommands` to return the commands matched with
the search
- `CommandMenuContainer` to simplify the `DefaultLayout`

- Unmounted the `CommandMenu` when it wasn't opened to improve
performances

I also introduced a new behavior: Automatically select the first item
when opening the command menu:
