Issue description

If you try to use the GDVIRTUAL functions (such as GDVIRTUAL0 or GDVIRTUAL0R) without "using namespace godot;" at the top of your file, they will fail to compile. If I expand the macro inline this seems to be due to the the line:
method_info.flags = METHOD_FLAG_VIRTUAL;\
If I change this inline to:
method_info.flags = godot::METHOD_FLAG_VIRTUAL;\
Then everything begins to compile fine without the "using namespace godot;" at the top of my .hpp file. This seems to apply to all GDVIRTUAL macros

Steps to reproduce

Setup a gdextension project with the godot cpp bindings
Create a class and add a virtual function through GDVIRTUAL0 (or any virtual macro)
Add the bind_methods for it
This will result in scons failing to build the class

Minimal reproduction project

N/A However, here is a simple .hpp file to reproduce the issue

#pragma once

#include <godot_cpp/classes/node.hpp>
#include <godot_cpp/core/binder_common.hpp>
#include <godot_cpp/core/gdvirtual.gen.inc>

//using namespace godot;

namespace Test
{
	class TestClass : public godot::Node {
	    	GDCLASS(TestClass, godot::Node)

		//Section for const private vars
		protected:
			GDVIRTUAL0(_TestFunction);
	};
}

Uncommenting the using namespace godot line will get rid of the error.
