This test need to be re-located

I move this test to be under CanvasRenderingContext2DTest, hope that is fine.

-{
-    RefPtrWillBeRawPtr<HTMLCanvasElement> canvasElement = HTMLCanvasElement::create(*Document::create().get());
-    canvasElement->setHeight(40);
-    canvasElement->setWidth(40);
-    RefPtrWillBeRawPtr<ImageBitmap> imageBitmapDerived = nullptr;
-    {
-        RefPtrWillBeRawPtr<ImageBitmap> imageBitmapFromCanvas = ImageBitmap::create(canvasElement.get(), IntRect(0, 0, canvasElement->width(), canvasElement->height()));
-        imageBitmapDerived = ImageBitmap::create(imageBitmapFromCanvas.get(), IntRect(0, 0, 20, 20));
-    }
-    CanvasContextCreationAttributes attributes;
-    CanvasRenderingContext2D* context = static_cast<CanvasRenderingContext2D*>(canvasElement->getCanvasRenderingContext("2d", attributes));
-    TrackExceptionState exceptionState;
-    CanvasImageSourceUnion imageSource;
-    imageSource.setImageBitmap(imageBitmapDerived);
-    context->drawImage(imageSource, 0, 0, exceptionState);
