### Godot version

v4.1.1.stable.mono.official [bd6af8e0e]

### System information

Godot v4.1.1.stable.mono - macOS 13.4.1 - Vulkan (Forward+) - integrated Apple M1 - Apple M1 (8 Threads)

### Issue description

After creating a `@tool` script that is autoloaded and uses Semaphores and a Thread, when exiting the editor it freezes and stops responding on MacOS.

Editor not responding after closing the editor:

The editor must then be force quit and produces the following error information:

A full minimal reproducible product is provided, but the important snippets are:
```
@tool
extends Node

var mutex: Mutex
var semaphore: Semaphore
var thread: Thread
var exit_thread := false


func _ready():
    mutex = Mutex.new()
    semaphore = Semaphore.new()
    exit_thread = false
    
    thread = Thread.new()
    thread.start(_thread_function)

func _thread_function():
    while true:
        semaphore.wait()
        
        mutex.lock()
        var should_exit = exit_thread
        mutex.unlock()
        
        if should_exit:
            break
        
       # Actual thread work goes here

func _exit_tree():
    mutex.lock()
    exit_thread = true
    mutex.unlock()
    
    semaphore.post()
    
    thread.wait_to_finish()
```

At first I thought that `_exit_tree()` was not being called when the editor closed, but I found that it is because placing a `ResourceSaver.save()` in `_exit_tree()` creates a file when the editor closes.

### Steps to reproduce

Create a `@tool` script using Semaphores and a Thread and set it as an autoloading script in-editor.

The [Using Multiple Threads#Semaphores](https://docs.godotengine.org/en/stable/tutorials/performance/using_multiple_threads.html#semaphores) guide can be used as a base.

### Minimal reproduction project

[Thread Tools Test.zip](https://github.com/godotengine/godot/files/12237193/Thread.Tools.Test.zip)

Note: I use a mono build of Godot, but this does not contain any C#.

Contains an autoloaded tool script that is a slightly modified version of the [Using Multiple Threads#Semaphores](https://docs.godotengine.org/en/stable/tutorials/performance/using_multiple_threads.html#semaphores) guide.

Also contains a test scene with a tool script where changing a number in-editor will post the semaphore to see that the thread is running correctly in the background.
