C# method tweens can't handle 64 bit integer types

Issue description

I wanted to create a Tween that interpolates a method in value range of a long type (64 bit). When the tweened method gets called with values outside the "classical" 32 bit number range (-2147483647 till 2147483647) the method gets only a constant value of -2147483647.

Surprisingly the last call of the tween passes in the correct value then.

Steps to reproduce

Use the code snippet on any Node C# script (it was a control node in my case):

public partial class CurrencyView : Control
{
	public override void _Ready()
	{
		this.SetValue(long.MaxValue);
	}
	
	
	public void SetValue(long value)
	{
		Tween tween = this.CreateTween();
		tween.TweenMethod(new Callable(this, MethodName.OnValueTweener), 0L, value, 0.8d);
	}


	private void OnValueTweener(long value)
	{
		GD.Print(value);
	}
}

Then just run any scene with a node in it that has this script attached.
You should see log with the wrong numbers:

-2147483648
-2147483648
-2147483648
-2147483648
-2147483648
-2147483648

This applies to GDScript as well

Will look into a fix, I think I know what the error is

Thank you for reporting, in the future please make sure that a bug is exclusive to C# before reporting for C#

True that. Just did not have any experience with GDScript yet but this would probably easily be adaptable. Will take care of that next time. 👍 Thanks for confirming.
