Class generated by the Autoload attribute has different namespace

[ErnSur]

Hello!
I discovered where Autoload attribute is used the source generator creates a class with the same name but in different namespace.
The documentation is explicit about it but I don't get why that would be the intended behavior.

Given:

namespace Foo;

[Autoload]
public static partial class Bar;

The following code is generated:

using System;
using System.ComponentModel;

namespace Godot;

static partial class Bar
{
    private static Node root = (Engine.GetMainLoop() as SceneTree)?.Root;
}

Expected:

using System;
using System.ComponentModel;

namespace Foo;

static partial class Bar
{
    private static Node root = (Engine.GetMainLoop() as SceneTree)?.Root;
}

Ah... Yeah, that is weird. The idea was that a Godot.Autoload class would be automatically injected so you wouldn't need to define it, but I can't see any reason why that has to be the case and it's quite different from the way everything else works.

Technically it will be a breaking change to fix it, but I think it in this case it is warranted. Thanks for picking up on this.

This is ready to go, but I'll inform other stakeholders before merging to main.

Just a heads up that this PR will remove the auto-generated Godot.AutoLoad class and you will have to explicitly decorate your own class with the Autoload attribute. This is more aligned with how other the generators work and I couldn't find any reason why this shouldn't be the case. Thumbs up if cool, otherwise let me know before I merge.
